Okay, after experimenting for a bit, I found that this works:

       writeln( map!( ( c ){
          return offset;
       } )( INPUT ) );

While this segfaults:

       writeln( map!( ( c ){
          return cast( dchar )( offset );
       } )( INPUT ) );

I guess this should go to bugzilla, right?
