I'm curious why you chose to nitpick - it's unlikely you didn't understand what
I meant.

Class instance types exist implicitly and are commonly represented by structs. 
The return type of std.typecons.scoped is an example, as you know. It is
reasonable to expect arrays (and, in general, sequentially stored objects) of
such structs to be usable. __traits(classInstanceSize) and
std.trait.classInstanceAlignment are used almost exclusively to calculate the
size/alignment for such structs. Neither produces results usable for that
purpose.
