[swift-evolution] multi-line string literals.

I think the proposal is very clear on its intended scope.
I really like this idea. It's readable, and it's as simple and uncluttered as I think it could be while still allowing the tabbing of new lines. The one thing I dislike about multi line strings in Ruby is how you have to left align each new line, which can really disrupt the visual flow of your code, especially if you are several tabs of indentation deep.
I would love to see the addition (at some point) of the ability to escape all whitespaces preceding the new line, if that line does not begin with a quote and thus is meant to be a direct continuation of the preceding line. That way you could maintain your indentation without adding whitespaces between what are meant to be subsequent characters in the string literal.

Once both features are available, they can be combined. For instance, using the `_"foo"_` syntax I sketch there for alternate delimiters, you could say:

Clearly this message is not getting through, but I'm not sure how I should edit the proposal to make it clear enough.
