I don't know. IIRC (big if), though, there was talk of adding support for "property behaviors"(?). Resetting lazy vars probably would've been one of them, and if so, it probably got pulled so that we wouldn't risk breaking source compatibility later by adding a consistent syntax for other behaviors. I think. I wish I could remember who'd brought up the idea... they'd probably know straight away if that's what happened.
