(I changed the issue title to better reflect where the discussion has
moved to)

I really like the approach of a custom internal type for the mantissa
storage (the module containing would probably best be called _decimal).
Then it should be possible to focus on letting C do what it does best
(high speed arithmetic) and Python do what it does best (provide the
nice API and context management features)
