oh yes! Ability to to use some InifinitePrecision class, or even
Boost.Rational numbers is very important.

Another question is the ability to switch underlying numerical data
types on runtime, which I think shouldn't be allowed - that would make
everything damn too complicated. I'm thinking now about free_quantity.
