Even if he is representing the devil, Ben raises a good point. To
summarize, the most recent set of suggestions that seem not to have been
completely shot down include:
np.filled_with((10, 24), np.nan)
np.full((10, 24), np.nan) # analogous to np.empty
np.values((10, 24), np.nan) # seems clear, concise
np.initialized((10, 24), np.nan) # a few more characters, but
# seems clear to me.
Personally, I like all of the last three better than the first.
