There are two groups of specs, the D language specs, and the specs of how dmd compiles D code. The vtable layout is a dmd spec, because in theory other D compilers can implement virtual functions in another ways (for example with dispatch tree, that are better for inlining, but have other disadvantages). D language specs show that D classes have the .__vptr and .__monitor properties, but I think the vptr can be just a ID pointer if a compiler implements virtual calls with dispatch trees, because there is no need of a virtual table.
