    use utf8; $_="foo"; /\X/ # runs fine
    As the utf8 manpage puts it,:
    WARNING: The implementation of Unicode support in Perl is incomplete. See the perlunicode manpage for the exact details.
    And in the perlunicode perldoc:
    WARNING: As of the 5.6.1 release, the implementation of Un +icode support in Perl is incomplete, and continues to be highly e +xperimental.
    So, I guess there are problems using extended unicode and that's why it's marked experimental.
