[Boost-users] partial specialization: mpl?

I have a function like: template<typename CharT> void foo() { std::basic_string<CharT> str; ... if(str=="bar") ... } I'd like to check at compile time if CharT is a char or wchar_t to specialize the string used to compare- MPL seems like the thing I would use for this but documentation on doing this seems scarce. Could someone give me an example? -- Cory Nelson http://www.int64.org
