Re: [Numpydiscussion] [Python3000] PEP 31XX: A Type Hierarchy for Numbers (and other algebraic entities)
Jeffrey, is there any way you can drop the top of the tree and going straight from Number to Complex > Real > Rational > Integer? These are the things that everyone with high school math will know.
I think knowledge of the concepts of group, ring, and field is supposed to be standard knowledge for any highschool senior  isn't this what the "new math" was all about?. Nah, AFAIK, not really. Of course, for those who remember Tom Lehrer, New Math was about learning that one could base number representation on

As far as the scientific disciplines which one might reasonably expect a college major therein to have at least a "nodding acquaintance" w/ the classes of Abstract Algebra, certainly Math (and hopefully Appl. Math and Stats), probably Physics, perhaps Chemistry, CS if you say so, but even Engineering I'd say you're beginning to tread in uncertain territory, and Biology, etc., unless taken with a large dose of formal mathematics, fuhgetaboutit.

But they're pretty fundamental to computer science; anyone trying to do serious work in the field (that is, anyone with a reason to read the PEP) should have a nodding acquaintance with them.
