So output should probably be a string[].

We're looking at:

enforce(output.length >= 2 && output.length <= 4.
    "Incorrect number of outputs passed");
enforce(["a", "b", "c", "d"].any(output),
    "Invalid value for output");

This is a one-time work per program. Granted, error messages could be 
nicer so that's a couple more lines. The gain from integrating such 
checks would be small.
