15. #### def flatMap[B](f: (A) ⇒ TraversableOnce[B]): Stream[B]

    [use case] Builds a new collection by applying a function to all elements of the outer stream containing this `WithFilter` instance that satisfy predicate `p` and concatenating the results.

    [use case]

    Builds a new collection by applying a function to all elements of the outer stream containing this `WithFilter` instance that satisfy predicate `p` and concatenating the results.

    The type of the resulting collection will be guided by the static type of the outer stream.

    B

      the element type of the returned collection.

    f

      the function to apply to each element.

    returns

      a new stream resulting from applying the given collection-valued function `f` to each element of the outer stream that satisfies predicate `p` and concatenating the results.

16. #### def foreach(f: (A) ⇒ Unit): Unit

    [use case] Applies a function `f` to all elements of the outer stream containing this `WithFilter` instance that satisfy predicate `p`.

    [use case]

    Applies a function `f` to all elements of the outer stream containing this `WithFilter` instance that satisfy predicate `p`.

    f

      the function that is applied for its side-effect to every element. The result of function `f` is discarded.

    Further refines the filter for this stream.

    q

      the predicate used to test elements.

    returns

      an object of class `WithFilter`, which supports `map`, `flatMap`, `foreach`, and `withFilter` operations. All these operations apply to those elements of this stream which satisfy the predicate `q` in addition to the predicate `p`.
