To be clear, the trouble I was trying to point at is that if foo.py didn't
have __all__, then it would still have a BB attribute. But if the module is
given __all__, the BB is normalized away into a B. This seems like pretty
strange/counterintuitive behavior. For instance, I found this bug when I
added __all__ to a mathy library, where other modules had previously been
happily importing BB and using <module>.BB etc. with no trouble.

In other words, I could accept "BB gets normalized to B always", but the
current behavior is "modules are allowed to have a BB attribute but only if
they don't use __all__, because __all__ requires putting the BB through a
process that normalizes it to B, and which otherwise doesn't get run".

If this is "working as intended" then w/e, I'll work around it, but I want
to make sure that we all understand the inconsistency before letting this
bug die in peace :-)
