internal: more reasonable grammar for blocks Consider these expples { 92 } async { 92 } 'a: { 92 } #[a] { 92 } Previously the tree for them were BLOCK_EXPR { ... } EFFECT_EXPR async BLOCK_EXPR { ... } EFFECT_EXPR 'a: BLOCK_EXPR { ... } BLOCK_EXPR #[a] { ... } As you see, it gets progressively worse :) The last two items are especially odd. The last one even violates the balanced curleys invariant we have (#10357) The new approach is to say that the stuff in `{}` is stmt_list, and the block is stmt_list + optional modifiers BLOCK_EXPR STMT_LIST { ... } BLOCK_EXPR async STMT_LIST { ... } BLOCK_EXPR 'a: STMT_LIST { ... } BLOCK_EXPR #[a] STMT_LIST { ... } 2021-09-26 04:12:57 -05:00			`STMT_LIST@18..21`
