... the use of o seems to be discouraged.

I only latched onto  /o because I was casting about for something to use in a manufactured example.

AFAIU, the  /o modifier is only useful now in those very limited cases in which one wishes to prevent recompilation of a  qr// m// s/// even when interpolated Regexp objects or strings have changed. My understanding is that these operators will not now recompile on each execution unless an interpolated regex/string has changed.

Give a man a fish:  <%-{-{-{-<
