Kenji (with help from others) has done many things on the writeln, like
improving string printing, improving array printing, significantly improving
associative array printing (maybe introducing xformat too). And I think he has
added the printing for lazy ranges. He has also improved or added the printing
of struct literals, improved the output in presence of const/immutable,
improved the function literals, and other important details.

That's mostly true for every improvement listed above. There is also
printf/puts.

considering how much common they are (and they are becoming) it seems a good
deal. (But they usually don't have chains of raw pointers).
