I have put together a rough example of what I have in mind. Please, find 
the code attached. It works on my GCC 4.3.

It converts integral types to strings and back, it also supports the 
"converter" functor that can be used with algorithms. Both of them 
support a couple of named parameters for customization. The 
implementation also has a fundamental support for further extension by 
adding new conversion tags and specializing the "converter_impl" 
template on them.

In order to inject new conversion tags into the library one has to 
overload "get_conversion_tag" function. I admit that it doesn't look 
very pretty, but it's a start, and it's non-intrusive. Maybe someone 
will suggest something better.

PS: I had to extend Boost.Parameter a little, but that's not too much 
and can be moved to Boost.Parameter if needed.
