[PATCH] Feature: @local declares local variables.

[Kaz Kylheku]

Hi All,

Taking into account mailing list feedback (Manuel, Neil, Ed)
and my own ideas, I have produced a new patch that introduces
both a @local statement, and a @local: variable annotation.

The patch switches the fparms array of a function from
being a dynamically allocated array of NODE objects to
being a dynamically allocated array of NODE * pointers.
This allows us to reallocate it to a larger size without
changing the addresses of NODE objects, which are
already entered into the symbol table and into the
byte-code objects.

The patch is more extensive, touching the debugger,
profiler and pretty printing.

I have added documentation, but test cases are still missing.

This is still discussion level, proof-of-concept stage.
