Nobody ever complained because PyQt4 is pretty preliminar, it hasn't yet seen a
single public release. I don't have a recent PyQt4 snapshot around, can you
post a list of those names? Some could be skipped when using the star import
(using __all__). It pretty much depends on what they are. hex() and oct() looks
like another serious problem that needs a solution, to me.
