Niko Matsakis	058abcc209	Place parenthetical notation under the unboxed_closure feature-gate. ... Consolidate the `unboxed_closure_sugar` and `unboxed_closure` feature gates.	2014-11-18 12:26:04 -05:00
Niko Matsakis	221edbae38	Support parenthesized paths Foo(A,B) -> C that expand to Foo<(A,B),C>. These paths also bind anonymous regions (or will, once HRTB is fully working). ... Fixes #18423.	2014-11-06 06:48:23 -05:00
Patrick Walton	7c00d77e8b	librustc: Implement the syntax in the RFC for unboxed closure sugar. ... Part of issue #16640. I am leaving this issue open to handle parsing of higher-rank lifetimes in traits. This change breaks code that used unboxed closures: * Instead of `F:|&: int| -> int`, write `F:Fn(int) -> int`. * Instead of `F:|&mut: int| -> int`, write `F:FnMut(int) -> int`. * Instead of `F:|: int| -> int`, write `F:FnOnce(int) -> int`.
