What is the meaning of the ", D"? It does not seem to make a
difference if it is omitted.
B must provide its own implementation of D. It can't simply use
A's implementation.
I assume that is another bug and has nothing to do with
interfaces...

import std.traits;
alias parentOfB = BaseClassesTuple!B[0];
void main()
{
static assert(is(typeof(cast(parentOfB)(new B)) == parentOfB));
assert((cast(parentOfB)(new B)).foo == (new parentOfB).foo);
}
class A
{
int foo() { return 1; }
}
class B : A
{
override int foo() { return 2; }
}
