I build a self-referential system, then tried to copy only parts. I need
to step back and adjust my approach.
'Toy_private_deepCopyValue' and 'Toy_private_deepCopyScope' need to be
ripped out, and I need to simply accept there will be only one instance
of 'Toy_Bucket' that isn't freed until the top-level VM is.
I need an hour's break before I'll tackle this again.
See #163
Functions are having issues with being copied around, especially
between buckets, leading to the scopes getting looped. The program gets
stuck in 'incrementRefCount()'.
It's past my time limit, so I'll keep working on it tomorrow with a
fresh mind.
All function stuff is still untested.
See #163
I had intended to solve the Advent of Code puzzles in Toy, but they
don't work without arrays. I wasn't able to enable arrays in time, so
I need to focus on doing things correctly.
The most immediate tasks are marked with 'URGENT', and a lot of tests
need writing.
