Eventually, it should -- and many other changes throughout Python, outside
of Decimal, should also be made.  That won't happen for the first release,
though, and possibly never if Decimal doesn't become popular.


+ Float format codes, like %20.6g, make fine sense for Decimal, but
  feeding them Decimals won't do any good.

+ A Decimal version of the math module doesn't exist.

+ Looking up context all the time is expensive, and should eventually
  become part of CPython's C-level thread state (much as your FPU's
  context register(s) are part of your C's runtime thread state).
