+error[E0005]: refutable pattern in local binding: `A(_)` not covered

+LL | let Foo::D(_y, _z) = x;
+ | ^^^^^^^^^^^^^^ pattern `A(_)` not covered

+ = note: `let` bindings require an "irrefutable pattern", like a `struct` or an `enum` with only one variant
+ = note: for more information, visit https://doc.rust-lang.org/book/ch18-02-refutability.html

+LL | let (_y, _z) = if let Foo::D(_y, _z) = x { (_y, _z) } else { todo!() };
