Thank you Antoine for your review.

To avoid discrepancy between re and regex (and other engines), I have committed only a part of dynamic patch, without adding support of backreferences with index over 99. It is unlikely to achieve this limit in hand written regular expression, and in generated regular expression you can use named groups.

I found that backreference syntax is one of most discrepant thing in regular expressions. There are at least 8 different variants (\N, \gN, \g<N>, \g{N}, \k<N>, \k'N', \k{N}, (?P=N)), and \g<N> in Perl have different meaning.
