`lines` , as a sub instead of a method, and no arguments.
See: https://docs.perl6.org/routine/lines#(Cool)_routine_lines
Without any arguments, sub lines operates on $*ARGFILES, which defaults
to $*IN in the absence of any filenames.
For example:
perl6 -e 'say .join("\t") for lines().rotor(4);' path/to/file.txt
Hmmm. I would expect that to be in the Perl 5 to Perl 6 Migration Guides, but I
do not see it there.
