Keegan McAllister	416137eb31	Modernize macro_rules! invocations ... macro_rules! is like an item that defines a macro. Other items don't have a trailing semicolon, or use a paren-delimited body. If there's an argument for matching the invocation syntax, e.g. parentheses for an expr macro, then I think that applies more strongly to the *inner* delimiters on the LHS, wrapping the individual argument patterns.	2015-01-05 18:21:14 -08:00
Patrick Walton	caa564bea3	librustc: Stop desugaring for expressions and translate them directly. ... This makes edge cases in which the `Iterator` trait was not in scope and/or `Option` or its variants were not in scope work properly. This breaks code that looks like: struct MyStruct { ... } impl MyStruct { fn next(&mut self) -> Option<int> { ... } } for x in MyStruct { ... } { ... } Change ad-hoc `next` methods like the above to implementations of the `Iterator` trait. For example: impl Iterator<int> for MyStruct { fn next(&mut self) -> Option<int> { ... } } Closes #15392. [breaking-change]	2014-07-24 18:58:12 -07:00
