Oh, I agree. It is just that the documentation is pretty adamant that

D is a systems programming language. By that I mean that there are
mechanisms to defeat the type system, for those that know what they're
doing.
If you defeat the type system, and mutate immutably-typed data, the
onus is on you. It's like if you pop the carburetor off and put a
supercharger on, you void the warranty <g>.
I hate having to keep argue this, but you keep forgetting. You cannot
create immutable data without circumventing the type system (except
strings which have special treatment).
Yes, this is a bug, and one not easy to fix (requires a bit of flow
control constructors), but we know how to fix it. It's just a matter of
time.
