This is an incredibly creative answer , if not fastidiously
correct.  Raw strings simply disable the special effects of
backslash (\) within the string (except that it cannot be
the final character of a quoted string even if it a raw string
for technical lexer (tokenizer) simplicity reasons).  The regex
syntax is used on the resulting string constant if (and only if)
the string is passed to the regular expression functions as a
regex pattern parameter.
