or even (a C# like explicit implementation would be a nice option 
to have in D:

interface Clickable
{
   void onClick();
}

class Component
{
   void render()
   {
       writeln("Rendering generic component");
   }
}

class Button : Component, Clickable
{
   void Clickable:onClick()
   {
       // First-time implementation of Clickable.onClick
       writeln("Button clicked!");
   }

   override void render()
   {
       // Overrides Component.render
       writeln("Rendering a button");
   }
}


--- And when it becomes even more confusing:

interface Isomething
{
   void someMethod();
}

class Base
{
   void someMethod() { }
}

class Derived : Base, Isomething
{
   override void someMethod() { } // ??

// Error: Method 'someMethod' matches both a base class and 
interface signature. Use override or explicit interface 
implementation to clarify."
