The default compare for structs is a bit compare of the contents.
Which definitely seems inherently broken. Doing that only works if the struct
only contains integral types, character types, or bool. Nothing else will
compare properly that way. It really needs to work like arrays do (or are
supposed to anyway) and compare each member according to == and only fallback
to an outright bitwise compare when it knows that the results would be
identical (i.e. because all of the members are integral types, character
types, bool, or other structs which hold only integral types, character types,
or bool - be it directly or in other structs that they hold). Bitwise comparison
is the is operator's job, not ==.

That will broke code.
But That is the way to go IMO. D needs to evolve to make things more
consistent in general.
Still not doable without a proper versionning scheme.
