Thank you for your answer; that appears to be what is happening. I figured it was due to my lack of knowledge about P::RD. I was puzzled by the way it appeared some of my test cases were rejecting the first rule without consequence.

    It's just like in regexps
    'XZ' =~ / ^ (?: X (?{ print "X" }) Y (?{ print "Y" }) | X (?{ print "X" }) Z (?{ print "Z" }) ) \z /x; print("\n");
