No, warnings overrides $^W/-w (regardless of their relative order).

Of course. I knew there was a good reason for not using warnings :)

$SIG{__WARN__} achieves my goal. Thankyou.

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