class Foo
{
...
     private void deleteMySelf()
     {
         for (int i = 0; i < foo.length; i++)
         {
             if (foo[i] == this)
             {
                 // If order is not important, copy last element of array  
to position i
                 //
                 //   foo[i] = foo[$-1];
                 //
                 // If order is important, iterate through rest of array,  
moving elements one step forward
                 //
                 //   while (++i < foo.length)
                 //   {
                 //       foo[i-1] = foo[i];
                 //   }
                 //
                 foo.length--;
             }
         }

         delete this;
     }
...
}


Foo[] foo;
