Ok. Realizing that all(1,4)!= all(1,4) helps me a bunch - thanks to all posters. As a followup, it seems to me that the docs must be in error when they imply that the following code could ever work... 

$ideal = any( 
  all("tall", "rich", "handsome"),
  all("rich", "old"),
  all("smart","Australian","rich")
);

while (@features = get_description) {
  if (any(@features) eq $ideal) {
    print "True love";
  }
}

After all, I think that it has been illustrated that an "n-all" where n>1 cannot eq anything. Am I wrong?

update: Of course, I am wrong about this. I must have had those Friday-morning blinders on. An "n-all" cannot eq an "n-all" of the same order (update: except if ni=C for 0<=i<=ordern-1 (e.g. all(1,1,1) == all(1,1,1)), but that doesn't mean that an any can't match "n-all" of order > 1. My bad.

upupdate: Fantastic! Now, I actually understand the Q::S operators. Many thanks to Tilly (and also for reporting the docs bug). I really had to struggle to get used to distributing the operator joining each composite superposition across the cross-products (or something like that!). Then, everything clicked (here's to hoping it stays clicked). Q::S is really a neat package, IMHO, but a bit of a mind-bender initially.
