[swift-users] Is "lazy let" on the schedule anywhere?

I myself highly want lazy constants (I’m tired of writing something like file private private(set) lazy var propertyName: ReferenceType just to hide the setter from the rest of the codebase), but I don’t think this will ever happen in Swift, at least not as an improvement for the lazy keyword itself. Joe Groff had a really awesome proposal last year, which is currently in a deferred state but will be resurrected in the future.
It’s simply is a prioritization question, when this will happen.
That said, I’d expect some kind of readOnlyLazy property behavior that will match the mentioned lazy let.

It sure would be nice if the compiler supported lazy lets for structs. Any idea when or if this will be supported?
Seems like a nice performance win, lazy var is a pain because you can't access arguments passed into a function without mutation complaints.
