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,
