I'd rather know what usage of MODULE->VERSION doesn't work for you (as I worked
rather hard to make UNIVERSAL::VERSION DTRT).  It may be that I did something
stupid or it may be that you are doing something stupid; either way, I would
rather fix that problem rather than papering over it.  ;-)

Although most are, all pragmas are not necessarily lexical (see 'constant' or
'lib' for example).  A pragma is merely a way of affecting *at compile-time* how
Perl operates, and they can have run-time effects as well (as does version.pm).
 The very nature of version.pm requires it to be global in nature because the
CPAN release is designed to make [very] old Perl's work exactly like the latest
Perl (5.10.0) when it comes to version comparisons.  Specifically, if you don't
have the upgraded UNIVERSAL::VERSION, certain $VERSION strings that would be
equivalent otherwise will show up as different.
