How to match specific modifiers of a method? In this example I want to match all public methods.

C#

class Bar {
    public static async void Fii() {
    }

    void Foo() {
    }
}

Rule:

language: csharp
rule:
  kind: method_declaration
  has:
    field: modifier
    regex: ^public$

Playground

The problem here is that users misused kind with field. We can generate an error for it.
