          Issue Type: Improvement
            Reporter: Olga Natkovich


Currently, it has the following code in processInput:

 if(rslt.size()==1 && rslt.get(0) instanceof Tuple){
                res.result = rslt.get(0);
 }

Note it does getInstance on every Tuple it process even though it should 
already know from the return type.
