Ah, well thanks. I don't think it makes much sense since it

Accessors are there only for the generation of the standard

that just get or set some object property.
Hmmm... that's a bit of a bummer because it helps only the
degenerate case (accessors are there as placeholders for future
extensions, and otherwise offer no protection whatsoever
compared to a public value). The question would be then what
would be use cases for the accessors. Predicated setters are
not just a random thing one might want out of many
possibilities, it's a frequent pattern. -- Andrei
Given that D supports class invariants, is there a real need for
predicated setters?
