> Each call to invoke allocates a new args []interface{}, but the common case
> is to run the same ProcessElement function over and again. It should be
> possible to have a container struct to retain the args slice, and avoid
> recomputing the indices for where to assign parameters before calling the
> ProcessElementFn.
