[boost] yet another multimethods library

Hi, i'm on the verge of completing a first release of a fully featured 
multimethods component for C++, one in which i believe goes beyond anything 
currently available and is very suited to become part of boost. I'm fully 
aware of Jesse Jones's contribution however his library has not become an 
offical part of boost and i believe my version takes things much further in 
thew different ways and i have some nice ideas for the next version to make 
even better.

It's inspired by boost/std::tr1::function and CLOS generic functions and 
thus works like bost::/std::tr1::function preferred syntax ALA function 
types e.g:

typedef boost::shared_ptr<fuzz> fuzz_ptr;

generic_function< void (const foo&, int, bar*, float,  fuzz_ptr) > foobar;

where foo, bar and fuzz are polymorphic types and automatically are 
considered for multiple dispatch, detection of which arguments are choosen 
for dispatch is automated (and yes there already is support for smart/proxy 
pointers/references in place with std::auto_ptr, 
boost::/std::tr1::shared/intrusive_ptr working out-the-box). The order and 
placement of arguments is irrelevant and non-polymorphic arguments are 
totally allowed, covariant return types comes for free and work similar to 
covariant return types of virtual member functions.

I think i'll just stop writing about the library any further (abit more to 
it than this) i just like to know if you guys are interested in making this 
an offical part of boost and to be worked on further by myself and with the 
help of others.

P.S By the way this has been built with boost mpl, preprocessor and type 
traits from the beginning and interlope with other boost components in mind 
i.e phoenix, lambda, fusion, bind, function etc, etc.
