I do think map() and filter() should issue a warning under -3 when the first arg is None. (Or does 2to3 detect this now?)
What's wrong with filter(None, seq)? That currently works in 3k:
<itertools.ifilter object at 0x2b5be60da450>
[x for x in _]
[1, 2, 3, 4]
But that's a bug -- it's been spec'ed that this will stop working. (Can't remember where, perhaps PEP 3100?)
I looked in 3100 and didn't see it.
(Side note, shouldn't we change the names for filter/map?)
Huh? What? Why?
The function name returned by repr: itertools.ifilter.
