Ehm...
Yes, it is a non-member function. No, it does not mutate s. It does return another set. It is purely functional (no side- effects).
Isn't the MPL doc clear enough? http://www.boost.org/libs/mpl/doc/refmanual/set.html
Patience, Joel. The whole functional thing is a bit unexpected in the runtime world for many C++ programmers. -- Dave Abrahams Boost Consulting www.boost-consulting.com
