The article on "Perl6 Answers" said that
we're going to propose a radical re-design of regex metacharacters
When something like this came up previously, someone commented that Perl's regular expression syntax had become the de facto "industry standard", and several other languages and libraries were emulating them and advertising "Perl-compatible regular expressions". It'll be a bit weird if Perl itself will no longer offer "Perl-compatible regular expressions".
