Correct yes but...

Personally I prefer anonymous subs if I never need to call them by name.

> line 50 : warn $message;

You should check the Perl-version, IIRC this causes an endless loop in Perl older < 5.8 (?) (Too lazy to look up when it was exactly fixed)

Newer versions are fool proof. ;-)

update

Talking about "generic solutions":

Please be aware that this approach doesn't help if the module in question is also recklessly overwriting $SIG{__WARN__}

Therefore a safe way of overriding is to create a wrapper, which calls the overridden handler from within (if present in $SIG{__WARN__}).

But you can only be sure after checking the source code of the module in question.
