        Why is this an issue?

        Specifying the default parameter values in a method call is redundant. Such values should be omitted in the interests of readability.

        Noncompliant code example

        public void M(int x, int y=5, int z = 7) { /* ... */ }
        
        // ...
        M(1, 5); // Noncompliant, y has the default value
        M(1, z: 7); // Noncompliant, z has the default value
        

        Compliant solution

        public void M(int x, int y=5, int z = 7) { /* ... */ }
        
        // ...
        M(1);
        M(1);
