You might find the filter() function in tye's Algorithm::Loops module of interest.

I always thought that it and the MapCar*() set of functions should have been in a separate module from the loops stuff where they might get seen. Maybe even included into List::Util

Examine what is said, not who speaks -- Silence betokens consent -- Love the truth but pardon error.
Lingua non convalesco, consenesco et abolesco. -- Rule 1 has a caveat! -- Who broke the cabal?
"Science is about questioning the status quo. Questioning authority".
The "good enough" maybe good enough for the now, and perfection maybe unobtainable, but that should not preclude us from striving for perfection, when time, circumstance or desire allow.
