Why would you loose interfaces and extern(C++)?
"struct" and "class" are interchangeable keywords in C++ (only
affects encapsulation). So not a lot more difference than POD
vs non-POD in C++?
There's a lot more difference in D. Classes in D are fat memory
chunks storing pointers to ClassInfo (inc. vtable), Monitor (i.e.
for "synchronized") and a list of all interfaces they implement,
that's before we get to data members. If we were to remove all
that, we'd lose the semi-natural way of interfacing to C++
classes, and some pretty horrendous code involving void* and
void** would have to be used.
