…-on-type-err, r=estebank Improve suggestion for calling fn-like expr on type mismatch 1.) Suggest calling values of with RPIT types (and probably TAIT) when we expect `Ty` and have `impl Fn() -> Ty` 2.) Suggest calling closures even when they're not assigned to a local variable first 3.) Drive-by fix of a pretty-printing bug (`impl Fn()-> Ty` => `impl Fn() -> Ty`) r? `@estebank`
