Make sure that macros that didn't pass LHS checking are not expanded. This avoids duplicate errors for things like invalid fragment specifiers, or parsing errors for ambiguous macros. Fixes #29231. 2016-05-18 13:08:19 +00:00			`macro_rules! baz(`
			`baz => () //~ ERROR invalid macro matcher;`
			`);`

			`fn main() {`
			`baz!(baz);`
			`}`
