I had to view Daniel Frey's mail as an attachment, but from reading it I have a question:

He suggested:

> {
> T nrv( lhs );
> nrv += rhs;
> return nrv;
> }

Why not use:

friend const T operator+ (const T& lhs, const T& rhs)
    return T(lhs) += rhs;

doing away with the named temporary, and possibly using normal return value optimization?
