* | Handle impl Trait more correctly | Florian Diebold | 2019-12-15 | 1 | -0/+31 |
| | | | | | | | When calling a function, argument-position impl Trait is transparent; same for return-position impl Trait when inside the function. So in these cases, we need to represent that type not by `Ty::Opaque`, but by a type variable that can be unified with whatever flows into there. | ||||

* | Fix coercion from &Foo to an inference variable in a reference | Florian Diebold | 2019-12-08 | 1 | -0/+37 |
| | | | | We didn't try to unify within the reference, but we should. | ||||

* | Don't unify within a reference | Florian Diebold | 2019-12-06 | 1 | -0/+36 |
| | | | | | | | If we are expecting a `&Foo` and get a `&something`, when checking the `something`, we are *expecting* a `Foo`, but we shouldn't try to unify whatever we get with that expectation, because it could actually be a `&Foo`, and `&&Foo` coerces to `&Foo`. So this fixes quite a few false type mismatches. | ||||
