> 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.
