Hmm, so if_ itself, with no arguments?  That’s a good idea.  I’ll try that.

That might be exactly what I was looking for, if it doesn’t choke the compiler.  Many thanks.

It turns out that this does work under VS2008.

Have you tried using injected names under VS2008? Like this:

 

template <typename T>

struct C

    : boost::mpl::if_<

        is_blue<T>,

        Ca <T>,

        Cb<T>

      >::type {

  C(blah& a, xxx b) : if_(a, b) {}

};
