Spoken like someone who hasn't had most of the above happen to them :) I've
had the first two happen to me multiple times already! As for the second
two, those will probably come up not matter what system is chosen. But
surely we can solve the first two (which are much more common, in my

Well, define "haven't had very many collisions." I've certainly never
"reported" mine, but that doesn't mean I haven't had them and been
frustrated by them! And even the stuff that's already in CPAN is kind of a
For example, is HTML::Mason really primarily an "HTML" thing? And just look
at the various OS-specific modules. The poor Mac:: modules are just sitting
out there hoping their top-level prefix doesn't get taken over by some
as-yet-unknown (but soon to be super-popular) protocol or product. And look
what happened when Mac OS X came along. We get MacOSX:: at the top level
too. Where's MacOS:: then? And does anyone really think LWP:: is a good
top-level name? With a good, standardized hierarchy, people could call
their modules by whatever fanciful "product names" they want, provided the
"LWP"-ish part is prefixed by something more conventional.

But what if they use Local:: and then want to use someone else's Local::
modules? (Say they purchased another company or are partnering with
someone.) What if they want to release their code to CPAN, despite the fact
that it may still be vendor-specific? (e.g. a parser for Acme's electronic
widget order receipt or something.) I think there are real problems to be
