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. 2011-09-13 15:50:03 +02:00			`// error-pattern: not all control paths return a value`

Allow tail expressions even in no_value blocks. Type checker will guarantee they have unit type. 2011-12-29 12:03:39 -08:00			`alt true { true { } };`
