Do you see that question at all in your quote above? As it is, it is rather
difficult making immutable classes in D, much because the OOP rules in D
has deteriorated lately, and the spec has as well. In addition there really
is no construct making any useful guarantees about constness, neither for
classes nor for code not using classes (which I'm well aware that you
abhor).
