Comment (by tscrim):
The `FreeMonoid` in the global namespace must be the `UniqueFactory`
instance for the old pickles to work, irregardless of which module or the
name of the class. That's the big problem. Or are you suggesting to just
leave `FreeMonoid` alone (or perhaps give it some warnings and
redirections when given other types of input)?
There is one other thing I thought of today, to implement a custom
unpickle override for `UniqueFactory`. I'm thinking this might be the best
way to work around this (and could easily create this on a separate
ticket). Thoughts?
