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.
