First, grep goes over the whole list. If you only need to stop at the first successful match, don't use it. You can use List::Util::first instead.

For this particular application, a bandpass filter rather than a low pass filter, List::Util::first is no substitute for grep.

( Actually, first() isn't even a low pass filter as it returns a single value not a filtered list but...)

Examine what is said, not who speaks -- Silence betokens consent -- Love the truth but pardon error.

In the absence of evidence, opinion is indistinguishable from prejudice.
