After thinking about this more, I think this more accurately captures the intention here, and is a more applicable name in other scenarios:
- `vec_case_match(needles, haystacks)` makes more sense
- `fct_case_match(new_lvl = haystack)` would make more sense since the LHS here is the resulting value, not the thing you switch on
- I seem to use "match" very frequently in the docs and the test descriptions, making me think that is the better name
