I’m also really looking forward to property behaviors happening.  That said, it is a huge amount of work to define and implement this feature with a lot of tie ins to other parts of the language.  I can’t imagine it happening this year.

Randomly, I suspect that they’ll be recast as “property macros” when they come back up for consideration. Perhaps our first hygenic macro?
