void main() {
   stdin.byLine(KeepTerminator.yes)   // 1
     .map!(a => a.idup)               // 2 '.' was missing start 
of this line
     .array                           // 3
     .sort                            // 4
     .copy(                           // 5
         stdout.lockingTextWriter()); // 6
}

On Windows you send EOF by using the Ctrl-Z key sequence.
