Re^2: *IN* Operator for the Perl wish list

Rather than "grep", I would use List::Util's "first" function, because that short-circuits on the first match, rather than always trying all of the elements.

I haven't benchmarked it, but I suspect first has significantly more overhead, so might only be of benefit for long lists. I'd be interested in seeing a benchmark.

Update: yes, I mean even the XS version

Not necessarily -- List::Util has XS versions of all its functions.
