Good. I'm not crazy after all :)

Excellent! The first method works as a drop-in replacement for me. Seems better
than the second, because it conserves named field access. The only slight
difference is this:
>>> a = map(np.asarray, x)
...but that doesn't seem to affect my code. Thanks a bunch for the quick solution!
