import std.stdio;

interface itest
{
  static void implemented_static()
  {
    writeln("static itest.implemented_static");
  } // ok

  static void empty_static(); // missing implementation
}

class A: itest
{
  // silently replaces the interface implementation - no warning/error?
  static void implemented_static()
  {
    writeln("static A.implemented_static");
  };

  // implements the empty static - error?
  static void empty_static()
  {
    writeln("static A.empty_static");
  };
}

class B: itest
{
  // static becomes silently an method - no warning/error?
  void implemented_static()
  {
    writeln("(method) B.implemented_static");
  }

  // static becomes silently an method - no warning/error?
  void empty_static()
  {
    writeln("(method) B.empty_static");
  }
}

int main()
{
  itest.implemented_static();
  //itest.empty_static(); // error

  A.implemented_static();
  A.empty_static();

  itest a = new A();
  a.implemented_static();
  //a.empty_static(); // error

  B b = new B();
  b.implemented_static();
  b.empty_static();

  return 0;
}

Tested with dmd2.0.57/Win32
