Introduce `scala.control` package?

[He-Pin]

Then migrate some classes in scala.util.control to scala.control and unleash the potential modulation of scala.util.

Like scala.util.control.NonFatal then wil be scala.control.NonFatal

[som-snytt]

I could imagine preferring scala.runtime to scala.util. I wouldn't pollute the scala namespace with control, however.

@som-snytt I believe scala.runtime is only for the runtime implementation generated by the compiler - it is not considered a stable, public API.

[som-snytt]

@NthPortal I was thinking of NonLocalReturnControl, but now I see it's already in runtime.

"Out of scope for Scala 2."
