Yes, this is answer to the question. By the way, it can be
simply
enum S = typeid(Whatever).init.length;
If exact type is statically known, no ClassInfo is required:
enum S = __traits(classInstanceSize, Whatever);
This is essentially what I'm doing BUT I am trying to avoid
having to repeat the exact same crap in every class because it is
time consuming, verbose, and error prone.
For those that care, here is a snippet of what I am doing. For
those that are bitches, GTFO. Remember, I'm a troll so everything
I say or do here is irrelevant, so I don't even know why you are
reading this in the first place.

Note that because it is a function call it is extremely expensive
compared to a compile time literal. Disassembly shows that the
actual size is a constant so the vtabl lookup and a function call
is all that is required. I'd like to minimize the overhead as
much as possible and, ideally not have to manually add the
template mixins to each class(it would be nice if it were
automated). I'm trying to reduce the costs of RT lookup as much
as possible(as I feel it is not necessary).
