It was ambiguous what Dean was +1'ing. I assume it was the removal of println() and print() and not a move to wstring.
I had previously mentioned making DOMString's semantics match that of a subset of wstring, so that a user could have a familiar behavior and it would be possible (though not tested and supported) that you could redefine DOMString to be derived from wstring. I haven't had any free time recently, but I could take a shot at scoping the effect. Is it worth trying?
