See this is Jun 2012 post on perl group speaking of unicode support on development branch:http://code.activestate.com/lists/perl5-porters/173477/Now, keep in mind, that std.regex had O(1) trie lookup for these things from day one, because inversion lists with O(lnN) lookup alone were too slow.
June 2012, eh? When you're done with it, can I borrow your time machine?
