Raymond Hettinger added the comment:

* Removed the dependency on itertools:  r61213.

* Fixed nasty cut-and-paste error in Callable:  r61214

Leaving the other one for Guido.  I suspect the __radd__ style methods
are can of worms best left unopened for now.  The right solution
probably involves visiting every piece of code in Python that makes a
concrete isinstance/issubclass test and replacing it with an abstract
test.  That may have unexpected side-effects, may be hard to test, and
may kill performance.
