assignment_to_method

Methods can't be assigned a value.

The analyzer produces this diagnostic when the target of an assignment is a method.

The following code produces this diagnostic because f can't be assigned a value because it's a method:

class C {
  void f() {}

  void g() {
    f = null;
  }
}

Rewrite the code so that there isn't an assignment to a method.
