Of course. Any answer to the question I did actually ask?

Sorry about that. I honestly didn't know and had to compile Rakudo Star (Perl 6) first in order to give it a try. And yes, you can cause all three terms to be evaluated by using parenthesis this way:

perl6 -e 'sub a{ say "moo"; 1 }; sub b{ say "yay"; 1 }; sub c { say "stuff"; 1 }; a() ^^ (b() ^^ c())'

This will output all three strings and not just the first two.
