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).
