Summary

Clippy doesn't catch that match arms are identical when using if on Some.

Lint Name

match_same_arms

Reproducer

I tried this code:

match Some(3) { Some(v) if v == 3 => true, Some(v) if v == 3 => true, _ => false,

I expected to see this happen: Clippy would catch that the arms are identical.

Instead, this happened: Nothing. Clippy didn't catch on.
