Right. Which is why I'd like to move the discussion over to
"How can we achieve this in D?"
I see two things that are in the way (aside from the obvious
things like non-@safe code): Casting away shared, and implicitly
shared immutable data. The former can be checked statically, but
the latter is harder to work around in the current language.
