Please clarify whether you plan to rely on all platforms having "the
same size and alignment constraints" for correctness, or whether that
observation of the status quo is only meant to reassure us that this
change won't cause memory to be wasted on padding.
If the former then I would feel very uncomfortable about the change.
Otherwise I think it will be a nice improvement in code clarity (and I
admire your ambition in taking on this project!)
