Just curious, why this change?
There was a problem hiding this comment.
Because in the existing test, the _is_paramaterized_ returns True when the class is actually not paramaterized (i.e. self.parameter is 0 and there's nothing to resolve).
As a result cirq.is_parameterized(val) returns False when val is actually parameterized and therefore the output of cirq.resolve_parameters(val) changes.
So this change fixes the test to make the behavior of _is_paramaterized_ and resolve_parameters consistent.
