When I was thinking about this very topic yesterday and today, I
came up with this problem:

  @strs = ();
  match /pat/, @strs;   # surprise!  I'm matching on $_

That is, how do you tell an empty array from no arguments?  I have
a horrible suspicion everyone is going to reach for lazy evaluation
and other magic.
