fix confusion in block expression parsing
...
closes #292
* if, try, while, for, comptime, defer are "greedy" with {} blocks,
meaning if their bodies are blocks, then no suffix operator is allowed
after the block. The {} block gets "built into" the containing statement,
like the body of a switch statement.
* the Expression syntactic element is no longer "greedy" with {} blocks,
meaning it's possible to have suffix operators after {} blocks without
needing the {} block to be an rhs operand first.
