   Ensure this is scheduled, but return something equivalent to the argument like the function par in Haskell.

   Ensure this is scheduled, but return something equivalent to the argument like the function par in Haskell. This can be used to combine two independent Producers in a way that ensures that the Platform will plan both into a single Plan.
