Agreed, it seems a shame that this would be an area where it's not
possible to introspect data that was available at compile time. (I'd
say it doesn't feel Pythonic, except that claiming that Guido's
proposing something non-Pythonic is self-contradictory :-))

However, I have no expectation of ever needing this data for anything
I'd write, so it's not actually something that would matter to me one
way or the other.
