undef local $SIG{INT} is clearer in intention than local $SIG{INT}
Allow me to disagree. I do not find it more readable, instead, I find this may qualify as obfuscation. This is not Perl. Well actually, it is, but I don't think it is normal Perl.

If you insist on explicitely showing that this value is set to undef, please use a more common idiom: 

   local $SIG{INT} = undef;

The explicit assignment is still unnecessary, but at least it looks more harmless.
