Fix several issues with the struct and enum representability-checking logic. 2014-10-06 02:20:25 -04:00			`use std::sync::Mutex;`

Further work is needed for the error reporting for non-Sized cycle cases; those currently just fallback to the old path. Also adjust tests. 2016-01-08 21:41:37 -05:00			//~^ ERROR recursive type `Foo` has infinite size
