I did try for the `removeListener` code (as performance is irrelevant there), but it was a poor fit for `switch` (duplicate cases, duplicate code, and can't do fall through or multiple options with `when` expressions it seems...)

If the benchmarks deem this a better implementation then it's fine. I was just wondering if it was missed.

The `removeListener` one is indeed not as appetizing.
