Log message:

      Added three things.
      
         - Return statements are now a control operation, returning
           from their function.
      
               f() =
                  if true
                     return 1
                  return 2
      
           f() now returns 1.  It used to return 2.
      
           If you want the old behavior, use "value" instead
           of "return".
      
         - Added checking for dead-code after return statements.
      
         - Sections no longer return their final value unless
           it is a "value".

Revision: 1182
Log message:

      Experimenting with variable scoping.
      
      This was an attempt to delay variable linking until runtime,
      which is desirable because you would like to have computed
      opens.
      
          open $(STDLIB)/foo
          X = 1
      
      It doesn't really work because when the definition of X is encountered
      at parse time, it isn't known what module it belongs to.  Since it isn't
      known, the variable summary for this file can't be computed.
      
      There are two solutions.
      
         1. Make the open static, so scoping can be determined
            at parse time.
      
               # Find foo using the static search path
               open foo
      
            This is the way most languages do it, but it is
            unsatisfying for omake.
      
         2. Keep dynamic opens, and keep a linkage section for each
            file that can be computed without evaluating the entire
            file.  It gets a little messy because of nested opens,
            but the nice thing is that opens are statically scoped,
            so nested opens do not affect the top-level definitions.
      
               open $(A)
               # link X, Y
      
               if blah
                  X = 1
                  export
               else
                  open $(B)
                  # link Y
      
                  Y = 1
                  export
      
               println($(Y))
      
      I'll try doing 2.

Revision: 1183
Log message:

      Ok, this is the first pass of adding separate variable scopes.
      It compiles, but I'm sure it doesn't work yet.
      
      This is option 2:
         - Dynamic open/include/export are allowed.  Each operation
           performs a link step.
         - There are 4 kinds of variables:
             - Private (statically scoped).
             - Protected (current object, dynamically scoped),
               access is limited to sub-objects.
             - Public (current object, dynamically scoped),
               access is unrestricted.
             - File (file object, dynamically scoped).
               Each loaded file has an associated object.
      
      During the link step, each unlinked variable is assigned to
      the appropriate kind.
      
      The language is still functional of course.

Revision: 1189
Log message:

      Continuing with experimenting with scoping.  This compiles and surely
      doesn't work.
      
      Here is the current model.
      
         - Kinds of variables:
              private : local to an object/file, statically scoped.
              protected : object fields, dynamically scoped.
              public : class fields, dynamically scoped.
      
           By default, variable definitions are protected.
      
         - Directives:
      
              include <file> : include the file as if it were inlined in
                 the current environment; you get public and protected
                 variables, but not private.
              open <file> : include at-most-once, in the Pervasives
                 environment, you get only the public variables,
                 the variables are *not* part of the current object.
              extends <file-or-object> : the usual inheritance directive,
                 like open, but protected variables become part of the
                 current object.
              import <file-or-object> : just get the file object.
      
           The <file> and <file-or-objects> do not have to be a constant.
           Linking is performed right afterwards.
      
           If the <file> is a constant, it defines an object
           of that name.  For example,
      
              open build/C
      
           will open the <OMAKEPATH>/build/C file, and it will also define the
           "C" variable.  If the filename is not a constant, this doesn't
           happen.
      
      Implementation:
      
         - There is a link step following an include/open/extends.
           Variables are references(!) that are set during the link step.
           It is only the variable names; the language remains functional.
      
         - Public variables are class variables.  This has little impact
           since the language is functional, but it does mean that some
           aliasing happens.
      
               X. =
                  public.foo = 1
      
               open $(X)
      
               Y = $(X)
               foo = 2 # This is the X.foo field
               println($(Y.foo))   # Prints "2"
      
           This would not be true for protected variables, but "open"
           has no effect on protected variables.
      
               X. =
                  protected.foo = 1
      
               open $(X)
      
               Y = $(X)
               foo = 2               # This is not the X.foo field
               println($(X.foo))     # Prints "1"
               println($(Y.foo))     # Prints "1"
      
         - Every object gets a public section for all its public vars.

Log message:

      I think I'm settling on this approach.
      
      Features:
         - All files have separate scopes.
         - Linking is dynamic, so you can change OMAKEPATH,
           or use computed values in open/include/extends/import,
           and everything should continue to work.
         - In default relaxed mode, you shouldn't see any change
           from what you do now.  However, it is possible to define
           a strict mode (I haven't done it yet).
         - public: fields can be modified.
           protected: fields are read-only when you open the object.
           private: fields local to an object, statically scoped.
      
      As usual, this commit is completely untested and needs to
      be cleaned up.

Revision: 1249
Log message:

      As you can no doubt see, this change was too extensive to commit
      to the trunk.
      
      The main change is to use marshal-safe hash-consing for files, dirs,
      and symbols.  The change is fairly minor, but it propagates to a lot
      of places.

Log message:

      Well, this was dumb, I completely obliterated the branch with the
      changes that I had made.
      
      I'll have to start another branch.
      
      This adds back support for phony targets.  They are now *really*
      scoped, so we won't get those bogus phony errors when a target
      changes from phony back to normal.

Log message:

      I don't know, somehow I get a "hyperref: conflicting options" on FC4.
      Maybe it is FC$, maybe it is some strange thing about my setup.
      In the meantime, use \def to forcably replace \href.
      
      Removed omake_bitvector, it is unused.
