C++ has probably the most flexible "gold standard" raw string literals.
As Alan I think rightly points out, this makes the language and all
tools that process the language more complex.  This is a high cost, so
the feature should deliver some real value.

For those that don't know, C++'s raw string literals can be as imple as
this for the string "raw-content":


But if the content itself contains the character sequence )" then the
programmer can specify any delimiter they want:


Sounds very similar to Ruby's heredocs or "Percent Strings" (and both of those have their own extra complexity because of allowed nesting).

Both are supported by ruby-mode with syntax-propertize-function without too much trouble.
