 Because our workflow ``Iris.Workflow.speciesLength`` has not been connected to a source or a sink, it in itself is still a function. If we build this workflow, we can see ``speciesLength`` alongside our other functions by using the ``list`` command:

 Often times you want to re-use a source or a sink without reconfiguring them. To do this, we can similarly separate the sources and sinks into separate workflows, like so:
