Correct yes but... > line 14 : local $SIG{__WARN__} = \&suppress_UV_warning; 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. ;-)
updateTalking 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.
