Andrei, I thought this was planned?

Bummer.  At least rvalues will be as fast as possible, and it will work as  
a temporary solution.

FWIW, I don't consider duplicating a function to be a good solution, we  
can do better.

But don't try doing opEquals without ref const, because the compiler won't  
allow it :)
