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
    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.

I'm not *in*-sane. Indeed, I am so far *out* of sane that you appear a
tiny blip on the distant coast of sanity.
