Bad example, I'll show a better one later.

Is there some reason to use assignment as your example? It seems a strange example, since we don't normally assign to const objects, nor build assignments that don't assign. 

Maybe a more motivating and less distracting example would be better.

Greetings,

How many time did we have to redundantly write the same member functions just to add a const version? Ex.:

struct A

{

    A & operator = (A const &) { return * this; }

    A const & operator = (A const &) const { return * this; }

};

What I would like to suggest would be to templatize those instances as such:

struct A

{

    template <qualifier Q>

        A Q & operator = (A const &) Q { return * this; }

};

This would in instantiate on-the-fly the 2 (or 4) versions of the same code.

Thank you,
