I've been reading to much Perl 6 stuff where Pairs are distinct entities. Your right. It's just a 2 element list in a void context which is being optimised away. Hence the '???'.

  • Posts are HTML formatted. Put <p> </p> tags around your paragraphs. Put <code> </code> tags around your code and data!
  • Titles consisting of a single word are discouraged, and in most cases are disallowed outright.
  • Read Where should I post X? if you're not absolutely sure you're posting in the right place.
