I filed http://bugs.python.org/issue24270 to track this, but there's a
fair bit of work to be done to integrate the changes into the existing
math module's code, tests and documentation.
I'm willing to consider a feature freeze exception for this, as long
as
it doesn't make invasive changes (it looks like it will
literally add one new entry point, which is acceptable)
it's cleaned up in the way the core devs are proposing
(integrate it into the math module, including tests and
documentation)
it's done before beta 2
Somebody, please take that as an encouragement to get this cleaned
up and ready for checkin.

p.s. Would it make sense to add a form of isclose to unittest?
