Got it. Parameter.add is what returns the task named "Add". Should have realized that there is no magic. Just need to get a list of the operators covered.
Operations defined for parameters: add, and, floordiv, ge, getitem, gt, hash, le, lt, mod, mul, or, pow, rand, sub, truediv.
Not sure how == is handled between Parameters.
Yeah, if x and y are Parameters, x == y does not compare the values. So don't use == in a condition of an ifelse.
