kotlinlang

Probably a long-shot, and feel free to shoot it down. Would you guys at JetBrains be opposed to implementing our `singleAssign()` delegate as part of the Kotlin standard library?  Our implementation is here on the TornadoFX project(<https://github.com/edvin/tornadofx/blob/master/src/main/java/tornadofx/Properties.kt#L52:L115>).  It allows making a property assignable only once and I've found it much more effective than `lateinit` since it locks down mutability and threading problems (unless you pass parameters to make it unsynchronized like `lazy()`)
