Returns a Stream of all elements

Returns a Stream of all elements

The element order is same as in the Idx itself

  val l: Idx[Char] = ('a' <> 'g').~.><

@scala.annotation.targetName("_addOpt")
def ++=(v: Opt[A]): Idx.Mutable[A]

Alias for addAll

Alias for addAll

Generally Opt could be added as a stream.

This overload is sligtly more efficient, but it also required for mapped Opt expressions, where Opt type is harder to resolve and it would not compile.
