And when a D compiler because of separate compilation can't de-virtualize a virtual class method call.

Can C devirtualize function calls? Nope.

Assuming a comparison to C++, you know perfectly well that D has a severe disadvantage. Unless people micro-manage final (I've never seen anyone do this to date), then classes will have significantly inferior performance to C++.

C++ coders don't write virtual on everything. Especially not trivial accessors which must be inlined.
