Misc. reader improvements, plus ability to run *.rla directly.
...
Fix tree_replace() to handle recursive data structures.
Fix some other minor bugs in the reader and interpreter.
Implement comment-escapes in the string parser, for more readable input.
Allow input program files (*.rla) to be invoked directly, with arguments.
Add a simple string->number converter as a builtin function.

Added built-in structure types and interpreter core (w/o bytecode).
...
Improved timing resolution by using clock_gettime() instead of clock().
Also gave project a name: Rosella. Play on 'Parrot' (Perl 6 VM).

Add support for weak boxes and wills/finalizers.
...
Also refactored some GC code into smaller functions.
Weak boxes and wills will be useful for implementing weak hash tables,
which in turn will be used to store dynamic parameters efficiently.

Add full support for remaining data type (box, vector, byte string).
...
Improve inline accessors for cases where value type is known.
Move GC stats into a single global structure to reduce proliferation of globals.

Refactor into a GC library (gc.c and gc.h) and a test program (gc_test.c).
...
Also, allocate GC memory ranges dynamically during startup (gc_init()) rather than statically.
