Looks like your Perl6/Raku code is missing the "-e" command line flag:
mbook:~ homedir$ perl6 ' my @x=<a b c D E F h i j>; for @x.rotor(3) -> ($,$,$third) { dd $third };' Could not open my @x=<a b c D E F h i j>; for @x.rotor(3) -> ($,$,$third) { dd $third };. Failed to stat file: no such file or directory mbook:~ homedir$ perl6 -e ' my @x=<a b c D E F h i j>; for @x.rotor(3) -> ($,$,$third) { dd $third };' "c" "F" "j" mbook:~ homedir$ HTH, Bill.
