I *knew* this was being specified somewhere, but I couldn't find it in either
the tracker or PEP summary.  As an aside Nick, what do you think about
splitting the pysystem proposal out of PEP 432?  I think they could certainly
live as independent PEPs albeit perhaps the pysystem one dependent on 432.

Perhaps!

We're getting pretty close to a real idea here. :)
