The obvious way to do this nan interning for floats would be to put the interning code into PyFloat_FromDouble. 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. -- Steven D'Aprano
