Aaron Hill e78e9d4a06 Treat trailing semicolon as a statement in macro call ... See https://github.com/rust-lang/rust/issues/61733#issuecomment-716188981 We now preserve the trailing semicolon in a macro invocation, even if the macro expands to nothing. As a result, the following code no longer compiles: ```rust macro_rules! empty { () => { } } fn foo() -> bool { //~ ERROR mismatched { true } //~ ERROR mismatched empty!(); } ``` Previously, `{ true }` would be considered the trailing expression, even though there's a semicolon in `empty!();` This makes macro expansion more token-based.		2020-11-02 13:03:13 -05:00
