The easiest way I could find right now seems to be:
>>> import pkg_resources
>>> dist = pkg_resources.get_distribution('foo')
Which isn't too bad and could be simplified into an even simpler API call.
If the package author doesn't set a __version__ attribute in his own
code, I'd be hesitant to magically make it available from the
accompanying metadata. If it's part of the metadata, an explicit API
that makes it clear that you are querying the package metadata seems
cleaner to me.
