[Numpy-discussion] Updates on NA / NaN values for Ints?

[Nick Eubank]

Thanks Nathaniel and Ben.

Nathaniel, I completely understand! Believe me, I appreciate all you folks
do already, and am hoping to some day improve my skills enough to
contribute myself.

Ben: they only handle it for Floats. If you introduce an NA to an int64
series, it just coerces the type into Float64.

With that said, someone on their list suggested they were going to try and
integrate it with dynd.

(ha! good catch Nathaniel -- sorry for double dipping, Internet initially
suggested they were waiting to see what the numpy team would do)
