C++ temporary variables in initialization list

Question

In C++, is there any way to have something like a temporary variable in an initialization list. I want to initialize two constant members with the same instance of something

Answer 1

In C++11 you could use delegating constructors:

class Baz{
    const Foo f;
    const Bar b;
    Baz(Paramaters p) : Baz(p, temp(p)) { } // Delegates to a private constructor
                                            // that also accepts a Something
private:
    Baz(Paramaters p, Something const& temp): f(p,temp), b(p,temp) {
        // Whatever
    }
};
