Sorry, please forget the above my post.
I noticed that the above one has nothing to do with .sort and doesn't match the
title of this issue.
$ perl6 -e 'for ((1, 2).Seq, (3, 4).Seq) -> ($k,$v) { ($k,$v).say; }'
Too few positionals passed; expected 2 arguments but got 0 in sub-signature
in block <unit> at -e line 1
