[Zope-dev] zope.testing: Define __add__ for RENormalizing

[Christian Zagrodnick]

Hi,

I suggest defining __add__ for zope.testing.renormalizing.RENormalizing 
which would return a new Checker with the transformers combined.

This allow better reuse of those checkers without having to define the 
patterns separately. Like

checker = checker_a + checker_b.

Comments?
