Is it by design that "numpy.sqrt(None)" raises an "AttributeError: sqrt"?
This was confusing because there was an attribute lookup of 'sqrt' in numpy right there in the expression I typed, but that was not the attribute that python was complaining about. I presume that numpy.sqrt didn't know what to do with None, so it looked up a .sqrt in it or something... but I presume this only in hindsight now that I figured out the problem--I didn't mean to take the sqrt of None in the first place. How about adding some information to the AttributeError, such as the object on which the lookup failed (here None, as opposed to the numpy module). Now I'm off to delete all the getattr(numpy, 'sqrt') calls I littered through a few files...
