On a best effort basis, point at the variant(s) that are missing. This does not handle the case when the missing pattern is due to a field's enum variants: ``` enum E1 { A, B, C, } enum E2 { A(E1), B, } fn foo() { match E2::A(E1::A) { E2::A(E1::B) => {} E2::B => {} } //~^ ERROR `E2::A(E1::A)` and `E2::A(E1::C)` not handled } ``` Unify look between match with no arms and match with some missing patterns.
