I considered adding it to util.py but that module mostly deals with the differences between python versions. Unfortunately, MultiDict and UnicodeMultiDict don't have the same base class. I've dug around WebOb further and may instead check for their common base (DictMixin) and for the presence of .mixed(). mixed() a WebOb specific extension, so the behavior would remain unchanged, but the code would clearer. Thoughts?
