The problem is that if you have static ifs and the like in the

I don't see how this would be any different than, say, using
__traits(derivedMembers, typeof(this)) in a struct/class
declaration.
That being said, I have never used CRTP in D so far, since
template mixins seem to be the better choice in almost all
situations.
