[swift-evolution] multi-line string literals.

As a long time user of Perl, for me the simplicity and lack of flexibility is the attraction
when it comes to “”” syntax ;) That’s a lot of documentation for just specifying a string.

Perl makes life difficult for itself due to it’s rather simplistic $var interpolation syntax
which means you frequently want an un-interpolated string literal. The situation is
far better in Swift with the more distinct \().

Can you think of anything that couldn’t be readily expressed using Python style “””?
