[swift-evolution] multi-line string literals.

[Leonardo Pessoa]

I'm not in favour of multiline strings. I believe such strings should be
stored in plain files and loaded as needed. It makes both the code and the
string cleaner to read and maintain. I've had experiences with many
languages that offer that resource and I could see what your code can
become in terms of maintainability when you have such feature on the
language.

-1 from me.
