Actually, it was Hans Meine, but no matter, I'll file "the __doc__ of the
instance is created from the docstring of the corresponding method with
_frommethod.getdoc. I'm sure that's where we can improve things (like
substistute `self `by `a`" and the "Because it's an instance,
help(numpy.ma.compress) gives the docstring of numpy.ma._frommethod instead"
as numpy tickets (I just thought you might be able to describe the problems
better, and, due to a deeper understanding, be a better point of contact for
the tickets - all I'll do is quote your above characterizations).
Thanks, Fernando, for filing the iPython issue.

Thanks, Fernando
