Break fold's circular reference during unwinding
...
This converts the AST fold into a resource that breaks it's own circular
reference (just a temporary workaround until GC), so that failure during fold
will unwind correctly.

Change convention for specifying referenced argument

It is now 1-based, rather than 0 based. (Seems more natural, and allows 0 to

Introduce new semicolon rules
...
- Loop bodies and resource constructors aren't allowed to have
trailing expressions anymore.
- An expression that ends* in a block without trailing expression can
can not be called, indexed, or subscripted.
- Only expression-statements that end* in a block without trailing
expression can omit their semicolon.
*) 'Ending in a trailing expression' is defined as being a block or
construct-ending-in-a-block (if, alt) that either ends in an
expression itself, or ends in another block-like expression that
has a trailing expression (by these same rules).

Be more strict about what constitutes a block expression
...
Blocks (or statements involving blocks) that end in a semicolon are no
longer considered the block-expression of their outer block. This used
to be an expression block, but now is a statement block:
{ if foo { ret 1; } else { ret 10; } }
This helps clear up some ambiguities in our grammar.
