 * **Fan-out**
 
- - ``Broadcast[T]`` – *(1 input, N outputs)* given an input element emits to each output
- - ``Balance[T]`` – *(1 input, N outputs)* given an input element emits to one of its output ports
- - ``UnzipWith[In,A,B,...]`` – *(1 input, N outputs)* takes a function of 1 input that given a value for each input emits N output elements (where N <= 20)
- - ``UnZip[A,B]`` – *(1 input, 2 outputs)* splits a stream of ``(A,B)`` tuples into two streams, one of type ``A`` and one of type ``B``
- - ``FlexiRoute[In]`` – *(1 input, N outputs)* enables writing custom fan out elements using a simple DSL
+ - ``Broadcast<T>`` – *(1 input, N outputs)* given an input element emits to each output

 * **Fan-in**
 
- - ``Merge[In]`` – *(N inputs , 1 output)* picks randomly from inputs pushing them one by one to its output
- - ``MergePreferred[In]`` – like :class:`Merge` but if elements are available on ``preferred`` port, it picks from it, otherwise randomly from ``others``
- - ``ZipWith[A,B,...,Out]`` – *(N inputs, 1 output)* which takes a function of N inputs that given a value for each input emits 1 output element
- - ``Zip[A,B]`` – *(2 inputs, 1 output)* is a :class:`ZipWith` specialised to zipping input streams of ``A`` and ``B`` into an ``(A,B)`` tuple stream
- - ``Concat[A]`` – *(2 inputs, 1 output)* concatenates two streams (first consume one, then the second one)

 One of the goals of the FlowGraph DSL is to look similar to how one would draw a graph on a whiteboard, so that it is
 simple to translate a design from whiteboard to code and be able to relate those two. Let's illustrate this by translating
