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);

+1, unqualified call to to_string is how Boost Exception converts to string arbitrary objects stored in exception objects. If you use this form and someone adds a UUID to a boost::exception, it'll appear correctly in the output from boost::diagnostic_information.

-1 a to_string() member is IMO much preferred for simplicity and the encapsulation perspective. Just like std::bitset<N>::to_string(). There seem to be no standard in Boost for this :-(, e.g. filesystem uses ::string(), format uses ::str(). -Thorsten
