I remembered Damian saying that pick does not only work on junctions,
but on arrays and hashes, too (and I even found his posting :):

Are the following assumptions correct?
  my $junc = 1|2|3;
  print $junc.pick; # "1", "2", or "3"
  print pick $junc; # same

  my @array = <a b c>;
  print @array.pick; # "a", "b", or "c"
  print pick @array; # same

What does pick return on hashes? Does it return a random value or a
random pair? (I suppose returning a pair is more useful.)
