or standalone function? AFAIK lexical_cast has a lot of overhead :(

Hmm, I haven't really given it much thought.  Since it doesn't need to be a member function, I would lean toward a standalone function.  Do any other libraries have a similar function?  I would likely create:

template std::basic_string to_basic_string(boost::uuids::uuid const& u);

as well as,

std::string to_string(boost::uuids::uuid const& u); std::wstring to_wstring(boost::uuids::uuid conts& u);

How about making explicit specializations of lexical_cast that would be faster than the general implementation?  That way the optimization is invisible.

Nevermind optimizations, I think that a simple function call is easier to use and more practical: std::string x=to_string(y). Lexical_cast is in a different domain altogether IMO, plus it has other issues, for example it can't use ADL.
