To further this point, editors today show me \n and \t and friends in a
different color, because they are escapes, and this visually tells me the
thing going into the string at that point is not what is literally in the
code. A raw string does not highlight these because they are no longer
escapes, and what you see is what you get.

Probably f-strings will be used most in short strings, but they'll also be
used for long, heredoc-like triple-quoted strings. It's not going to be fun
picking expressions out of that when the wall-of-text contains no visual
cues.
