Note however that as I understand it D does not have "immutable
types" as claimed by patent 20140196008. The difference is that
according to the patent the immutable attribute is given to the
type
and applies to all instances of this type, whereas in D the
immutable attribute applies to an instance (I may be wrong about
that one, since I haven't done anything in D for years even if
I try
to keep up with the forums).
However, scala case classes should constitute prior art for
this
patent.

In D it applies to type. When you "apply immutable to the
instance" you in fact create new type on the fly by adding
immutable qualifier to the existing one. But it can also be
aliased to always be immutable.
