I've read both of the available printed D books in their

(circa ~2010) mentions that the D compiler rearranges the
members of `class` objects to be more optimal by reducing
alignment-induced padding whereas it leaves the
alignment-induced padding of `struct` objects exactly the same
as implied and required by the order in which you've written
the members of the struct.
Lots of things changed since Andrei's book.

struct alignment, right?
The answer is yes - D has a nice way of controlling the
alignment. - Here is a relevant section that explains it in fine
details: https://dlang.org/spec/attribute.html#align
