  9. trait Curried extends CurriedWithTypeParameters

    A marker trait that enables curried varargs.

    A marker trait that enables curried varargs.

    Given a function call f(a, b, c), when f is a subtype of Curried, it should be rewritten to f.applyBegin.applyNext(a).applyNext(b).applyNext(c).applyEnd.

    Optionally, some arguments to a Curried call may be a sequence argument marked as _*. Given a function call f(p1, s1: _*, p2), when translating it to the curried form, the sequence argument will becomes a foldLeft call.

    f.applyBegin
  .applyNext(p1)
  .applyNextSeq(s1)
  .applyNext(p2)
.applyEnd

    Unlike traditional repeated parameters, which restrict the sequence argument at the last position, sequence arguments in a curried call are allowed at any position.

    When a Curried is invoked with some type arguments, those type arguments will be moved to the applyBegin method. Therefore, List[Int](1 to 3: _*) should be translated to (1 to 3).foldLeft(List.applyBegin[Int])(_.applyNext(_)).applyEnd.

    Example:

    1. Fast list builder

      class PartiallyAppliedInitializer[A](builder: collection.mutable.Builder[A, List[A]]) {
  def applyEnd = builder.result
  def applyNextSeq(seq: Seq[A]) = {
    builder ++= seq
    this
  }
  def applyNext(a: A) = {
    builder += a
    this
  }
}
object FastListInitializer extends Curried {
  def applyBegin[A]:PartiallyAppliedInitializer[A] = new PartiallyAppliedInitializer(List.newBuilder[A])
}

FastListInitializer(0, 4) should be(List(0, 4))
FastListInitializer[Int](0, 100 to 103: _*, 1) should be(List(0, 100, 101, 102, 103, 1))
