Florian Diebold	6e1c2d0df8	Handle impl Trait more correctly ... 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.	2019-12-15 18:56:38 +01:00
