In short, a PEP is a summary of a long discussion. IMHO a PEP is required to write down the rationale and lists most important alternative and explain why the PEP is better.

The hard part is to write a short but "complete" PEP.

I tried to follow this discussion and I still to understand why my proposition of "def clamp(min_val, value, max_val): return min(max(min_val, value), max_val)" is not good. I expect that a PEP replies to this question without to read the whole thread :-)

I don't recall neither what was the "conclusion" for NaN.

So I suggest that either Neil (because it was your idea) or Steven (because you've had a lot of opinions, and done a lot of the homework) or both, of course, put together a reference implementation and a proposal, post it here, and see how it flies.
