in reply to OO Slip-up Preventor

Rather than $_[0]->isa I'd write UNIVERSAL::isa($_[0],__PACKAGE__) because if your first argument is "" or "\t", just to give two examples, then your code dies.

    I find that silly. Why does Perl allow "what a croc"->isa('foo'), but doesn't allow " what a croc"->isa('foo')? I find that highly shifty. (Harumph.)
