…stebank check_match: improve diagnostics for `let A = 2;` with `const A: i32 = 3` For example: ``` error[E0005]: refutable pattern in local binding: `std::i32::MIN..=1i32` and `3i32..=std::i32::MAX` not covered --> $DIR/const-pat-non-exaustive-let-new-var.rs:2:9 | LL | let A = 3; | ^ | | | interpreted as a constant pattern, not a new variable | help: introduce a variable instead: `a_var` ... LL | const A: i32 = 2; | ----------------- constant defined here ``` r? @estebank cc @matthiaskrgr@rpjohnst
