in reply to Named capture backreferences cannot be used in character classes?

qr[(?:"[^"]+"|'[^']+')]

For this example, that is shorter than your regex.

UPDATE: and you can automatically generate this:

my @class = ( "'", '"' ); my $re = "[(?:".join("|",map{"${_}[^$_]+$_"}@class).")]";

    Except I need to retain knowledge of the quote type, so: qr[(?<FQ>")[^"]+"|(?<FQ>')[^']+']; but that's fine.
