I think this is good way to proceed. This proposal will make it easy to switch
BigNum implementation.

Many users very much want a BigNum but don't really care much about efficiency
(but there are others who care very much indeed).

It would allow those who cannot use the best GMP bignum (because it has the LGPL
licence) to use a Boost.BigNum  - and would make this much more useful.  Kevin
Sopp has been promising to finish his promising Boost compatible version for
some time - hint!.
