I suppose that means I could do something like

alias array short[]
{
   ...
   short[] opAdd( short[] other )
   {
     ...
   }
}

short[] gimmeAnArray( short[] foo )
{
   short[] newArray;
   for ( int i = 0; i < foo.length; i++ )
     newArray ~= i;

   return foo + newArray; // usage of extension on short[]
}

That would be cool.  Though it would be nice if it didn't also stick an 
"array" type out there (does it?).  Is there anywhere I can find a 
complete look at what you're proposing?
