Jeffrey Seyfried 9bb3ea0feb Rollup merge of #34436 - jseyfried:no_block_expr, r=eddyb ... To allow these braced macro invocation, this PR removes the optional expression from `ast::Block` and instead uses a `StmtKind::Expr` at the end of the statement list. Currently, braced macro invocations in blocks can expand into statements (and items) except when they are last in a block, in which case they can only expand into expressions. For example, ```rust macro_rules! make_stmt { () => { let x = 0; } } fn f() { make_stmt! {} //< This is OK... let x = 0; //< ... unless this line is commented out. } ``` Fixes #34418.		2016-06-26 02:20:14 +00:00
