Optional is a microscopically small (6 lines) library for Scala to provide a variant of
that provides an implicitly defined value. Instead of
def foo(x: Option[Int]) = x.getOrElse(-1) foo(Some(123))
You can now write
import de.sciss.optional._ def foo(x: Optional[Int]) = x.getOrElse(-1) foo(123)
This is useful for some DSLs where you want to minimise noise for the user.
