The user of the Bits class is only lightly affected. The only change
she possibly should make is to add an extra Num constraint to the
existing Bits constraint.

Bits instances are more affected because they now need to add:

  bit = ...
  testBit = ...
  popCount = ...

where they could possibly use the supplied default functions.

Do you think these are show-stoppers?
