With this approach, the author of the custom function will need to remember to increment the counter, right? Also, I am wondering what is the difference between appending an incrementing counter in JState vs just appending a constant for every node ( NULL or NOT NULL ) ? appending some constant or null-term to the hash: <expression 1> <0><expression 2> <0> <0> vs appending an incremented value: expression_1 <1> expression_2 <2> <3> Both will do the job of adding the required entropy -- Sami
