If no arguments are given to `vec!` then no pushes are emitted and so the compiler (rightly) complains that the mutability of `temp` is never used. This behaviour is rather annoying for users.

feat: Implement `feature(exhaustive_patterns)` from unstable Rust Closes rust-lang#12753 Recognize Rust's unstable `#![feature(exhaustive_patterns)]` (RFC 1872). Allow omitting visibly uninhabited variants from `match` expressions when the feature is on. This adjusts match checking to the current implementation of the postponed RFC 1872 in rustc.
