The IMAP protocol uses a similar kind of construct (the length is
enclosed in braces)

Even ignoring the maintenance difficulty, I don't think it's possible to
syntax highlight something like that on most common editors.

The best solution I can think of is to have a text editor designed to
parse a string literal, spawn a nested editor with the unescaped
contents of that string literal, and then re-escape it back to place in
the code. If we had that, then we wouldn't even need raw strings.
