introduce `negative_impls` feature gate and document They used to be covered by `optin_builtin_traits` but negative impls are now applicable to all traits, not just auto traits. This also adds docs in the unstable book for the current state of auto traits. 2020-01-09 10:56:38 +00:00			`#![feature(negative_impls)]`

Fix bug in test for E0199 and add test for E0198. In particular, as far as I can tell from the error diagnostics, the former test for E0199 was actually a test for E0198, and there was no test for E0198. (I am assuming that one of my previous changes to the `unsafe impl` checking fixed a latent bug in how these two cases were differentiated.) 2016-10-12 14:53:57 +00:00			`trait Bar { }`
