Yeah, that's pretty awful. ;-) Maybe a more reasonable example::
# skip the first line
for line in iter(fileobj)[1:]:
....
where currently you'd write::
# skip the first line
fileobj.next()
for line in fileobj:
...
I'm floating around -0.5 on this one. The itertools functions I use
most are chain(), izip(), and count(). None of these are particularly
natural as a method of a single iterator object.

tiny blip on the distant coast of sanity.
