I was just playing around with junctions a bit today, and I noticed that if you weren't religious about using parenthesis with them you could get quietly tripped up:
say so any(<a b c>) eq any(<c d>); # True (as expected)
say so any(<a b c>) eq any(<d e f>); # False (as expected)
say so any <a b c> eq any <c d>; # False (something's wrong)
Basically, you need the parens on that first use of any.
Is there a reason you don't at least get a warning if you don't?
