Wait... you can do that? It's internal to iterencode, at least in
Python 3.3 and 2.7 that I'm looking at here. Can you share your code
please? I'd like to try that! When I first looked at the docstring, I
was thinking "Ah, can I override the bit that emits NaN to return
\"N/A\" instead?", but the code made me think that's not possible.
