in reply to Benefits/Disadvantages of version Object/version.pm

$VERSION Archeology has info on $VERSION styles commonly used, and one comment remarking on version.pm being hard to use.

There was a p5p thread: UNIVERSAL::VERSION and version.pm, that discusses various version.pm oddities.

I'd be inclined to stick to old school $VERSIONs, simply because there's more useful things to work on.
