No.

The reason extern(C++) classes work with -betterC and extern(D) does 
not, has to do with vtable's, not what members is in Object.

Anyway, even if extern(D) classes did work with -betterC, you won't get 
the standard library working with -betterC as a whole. Simply because it 
wouldn't be compiled in.

Of course one of the big issues with getting phobos working with 
-betterC is exceptions. There is no alternative and they require runtime 
stuff that just can't exist without a runtime.
