See the following result: $ perl6 -e '["1:0.470572470261861", "2:0.579981821025709"]>>.split(":", :skip-empty).sort({ $^b[0] <=> $^a[0] }).perl.say;' (Seq.new-consumed(), Seq.new-consumed()).Seq I think if sort method cannot look (i.e. consume) a Nth-indexed value (e.g. $^b[0], $^b[1], ...) and this behavior is a specced one, it should return a warning message. $ perl6 --version This is Rakudo version 2017.03-217-ge681498 built on MoarVM version 2017.03-115-ge8231a3 implementing Perl 6.c.
