No need to go that far.void fn(const A, A) {...} A a; fn(a, a); // what do you expect here? As far as i know D/C++ have the same treatment for const member functions. It has been this way forever.
Yup. It's why I think it is worthwhile that I spend time in this thread explaining things over and over. There are a lot of mistaken assumptions and baggage people carry around about const in both D and C++.
(One of the ironies of C++ const is that programmers assume it behaves like D const/immutable, but rely on it not doing so.)
