Fallout: tests. As tests frequently elide things, lots of changes here. Some of this may have been poorly rebased, though I tried to be careful and preserve the spirit of the test. 2015-02-12 10:29:52 -05:00			`use std::marker;`

Detect cycles and specialize error reporting for Sized. It is important to get the `Sized` error usable, since that hits new users frequently. 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
Fix several issues with the struct and enum representability-checking logic. 2014-10-06 02:20:25 -04:00
