librustc: Always parse `macro!()`/`macro![]` as expressions if not followed by a semicolon. This allows code like `vec![1i, 2, 3].len();` to work. This breaks code that uses macros as statements without putting semicolons after them, such as: fn main() { ... assert!(a == b) assert!(c == d) println(...); } It also breaks code that uses macros as items without semicolons: local_data_key!(foo) fn main() { println("hello world") } Add semicolons to fix this code. Those two examples can be fixed as follows: fn main() { ... assert!(a == b); assert!(c == d); println(...); } local_data_key!(foo); fn main() { println("hello world") } RFC #378. Closes #18635.
