Here's some experimentation by me to see how it could look in libbitcoin:

http://ideone.com/01YG2K

Notes:

* Every free function would become templated.
* I am looking for a way to avoid having different semantics for classes
to refer to values (currency_->some_value()) vs for functions
(Constants::some).
An option is to make classes templated too, and then libbitcoin would
become a nearly totally header only library (like the standard library).
