For compatibility with the Python version, I recently changed the rounding
constants of the C version to strings. This was at the request of a user
who wanted to exchange (Decimal, ROUNDING) pickles between the versions.

I think the strings are working fine and personally I have no plans to
change the type again.

The episode shows that pickling backwards compatibility is one thing
to consider, but I'm probably stating the obvious here. :)
