Right, it finds only one VERSION per file, but does so for any .pm
file you're interested in.

Indeed I correct you: PAUSE took the middle way and in all the years
only about 3 people complained: find N package statements in all *.pm
files but only one VERSION statement per file. You get an M:N matrix
of package name and version numbers, take the max of available version
numbers per package. Very trivial and effective.

Note that this was defined to be the correct way, even if thinge like

  package Foo::Bar;
  $VERSION=42;
  package Foo::Bar::Baz;
  $VERSION=123;

could surprise somebody who had the weird idea to write such a version
hell. We ruled out quite a lot of weird ideas that way.

So if you replace PAUSE's heavy weaponry in
PAUSE::pmfile::parse_version with plain MakeMaker->parse_version,
you're done.
