The context parameters KEEP (which btw, in hindsight, is good naming since it's in-line with other languages, and it highlights that they really do act like parameters) explicitly doesn't support delegates with contexts right now. Has there been any thought about them anyway? I really disliked the semantics in CR because the contexts on 
getValue
 and 
setValue
 were practically useless (since they're the same ones you can capture in 
provideDelegate
). Is there a world where `getValue`'s contexts correspond to `get`'s contexts, and analogously for 
set
?
