There is also no regexp escaping of single quotes either.  The only 
regexp escaping you can see are the \\\\ which translate into \\ in the 
string which is a literal backslash for the regexp engine.

It's not parenthesis around character classes but around the alternative 
of "match a backslash followed by any char" and "any char which is not 
backslash or the opening quote type of this string variant".
