I think, almost everyone of us at least had the feeling once that, to patch a software too often, you rather just redo it.
Perl 5 is an elegant language, even today. Its simpilicty and high performance is sort of fatal attraction for everyone.
However during those years, the programming world has largely changed, the need for Perl to either evolve itself or jump to Perl 6 is quite clear. My personal view is that, to patch is not the way to go, although may work for a while, it will not last too long.
