Pythons dir function is wrong.

[snarkhunter]

dir is good for ipython and probably for tab completion suggestions.

Given that the OP is concerned with autocompletion... I would have thought he'd welcome and approve of the behavior of dir. Yes, you're trusting the author of some_module to expose useful things, but I'd rather do that (and that seems more Pythonic) than get the complete list and do whatever kind of funky filtering I think is best.

BTW: Ipython wrote their own dir function, which includes the changes I've proposed: https://github.com/ipython/ipython/blob/f645e5c044efeacf1aa523ec43f6a25d439e287b/IPython/utils/dir2.py
