sort_constructors_first

Constructor declarations should be before non-constructor declarations.

The analyzer produces this diagnostic when a constructor declaration is preceded by one or more non-constructor declarations.

The following code produces this diagnostic because the constructor for C appears after the method m:

class C {
  void m() {}

  C();
}

Move all of the constructor declarations before any other declarations:

class C {
  C();

  void m() {}
}
