If defined in the same source file, allow static binding method to be a sibling of the class it provides.

For example: Consider a static binding method inside a nested class A:

class Outer {
  static class A {
    @Inject static A createA() { return new A(); }
  }
}

We can now choose to define createA directly in Outer:

class Outer {
  static class A {}
  @Inject static A createA() { return new A(); }
}
