In principle, there is no reason why *both* of these groups of users can't use one tool and be happy. I propose to establish a convention in PEP 8, explaining that, while both literals are semantically equivalent,

- r'..' strings *should* be used for regexps,

- R'..' strings *should* be used for unstyled raw strings,

and tools *should* treat them as such.

All of this is merely about codifying the current status quo.

What about all the regexps that are written without raw strings? Won't PEP 8 codification shame everyone into turn them into raw strings when they really don't need to?
