It is such a "Bad Thing" because it would reduce the power of CPAN. The community feels very strongly that what we have definitely needs to stick around.
BUT . . . it doesn't have to be the only thing. If you want to set up an easier way to find and install modules, go right ahead! In fact, if you're willing to put in some work, I'm pretty sure Andreas would love to have help with CPAN. I've discussed some things with him in the past and he's a great guy to work with. Just talking about it doesn't help anybody. Go ahead and do it. Just make sure it's compatible and life is good.
As for Win32, check out Strawberry Perl.
My criteria for good software:
- Does it work?
- Can someone else come in, make a change, and be reasonably certain no bugs were introduced?
