I'm kind of iffy on this mostly because I don't like the "unspecified" nature of things like this. That being said, if others find this useful I have a few comments:

1. This needs to be documented somewhere (likely in the langref)
2. Why just `nan` keyword? The general float formatting IIRC also allows for representing things like `snan` and nan with a payload. That would help a bit with covering the spectrum of specifying the behavior.
