The obvious way to do this nan interning for floats would be to put the interning code into PyFloatFromDouble. I'm not sure whether this would be worth the cost in terms of added code (and possibly reduced performance, since the nan check would be done every time a float was returned), but I'd be willing to review a patch. I hope that it's obvious from my previous post that I do NOT want such interning done, but since I put the idea in people's heads, I wish to reiterate that I'm against the idea: -1 on interning NaNs. For the rare application where it might be useful, it is easy to do in the application code.

Yep, and I'll freely admit I didn't know about the potential additional state on NaN values, or I wouldn't have suggested interning automatically.

Cheers, Nick.
