[swift-evolution] multi-line string literals.

What I'm actually suggesting is that comments *before* the continuing quote would be honored without terminating the literal:

let xml = "<?xml version=\"1.0\"?>
          "<catalog>
          "	<book id=\"bk101\" empty=\"\">
//          "		<author>\(author)</author>
          "	</book>
          "</catalog>"

A // or /* after the continuing quote would still be part of the literal.

I'm preparing a second draft without that feature, though, so if you still think it's a bad idea, I'll drop it.
