I can't answer for other core devs. My *guess* is that there's a reasonable chance that a well-written PEP for this would be accepted, but that's just a guess.

For myself, I'm not opposed to the addition, but neither am I yet convinced it's a good idea; call me +0. The number of bad prime-checking and factorisation algorithms that turn up on Stack Overflow (and not just in the questions, either) is enough to convince me that it's worth having _something_ basic and non-terrible for people to use.

I *am* strongly opposed to adding an imath module without first having a PEP - many aspects are unclear and in need of wider discussion. I unfortunately don't personally have sufficient time and energy available to push a PEP discussion through myself.

If you want to take this further, restarting a discussion on the python-ideas mailing list may be the way to go. It may still be worth drafting a PEP first, though: a draft PEP would likely help guide that discussion, and perhaps avoid it going totally off-topic.
