If D didn't have built-in OOP features already, it'd be an

You also loose loads of stuff like extern(C++) classes interop and
COM. Definitely a net negative. Even with a concept like signatures,
you just can't replace the class/interface system.
Even in betterC? Last I checked classes pulled TypeInfos and all the
stuff. What's the problem to use COM without classes? I do it.
Being able to define and use COM as it was intended (via classes) is a
feature of D.
Looks like it could be pretty straight forward to get it working in
-betterC, since what it isn't complaining about is TypeInfo. Keep in
mind, IUnknown is its own root, just like Object and has a completely
different ABI for vtable's and such.
