You can also just do 
    grep $_ == $value, 1,5,21,99;

which isn't much more typing.

    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.
