In Ruby, at least, there's a functional difference. Using single-quotes is a good way to indicate that a thing is just a string and not a template.

  That's true. There's also the subtler functional difference in both languages that single quote strings can have unescaped double quotation marks in them and vice versa.

    Ha, that's a good point.
