This is not a substantial issue regarding Perl 6, but is more a minor
feature curiosity/meditation. It was inspired some time ago by this PM
node:
http://perlmonks.org/?node_id=509310
I was wondering if in addition to push(), pop() etc. there could be be
rot() and roll() methods that would act upon lists (not modifying them)
like thus:
(qw/aa bb cc dd ee/).rot(2) # qw/cc dd ee aa bb/
(qw/aa bb cc dd ee/).rot() # qw/bb cc dd ee aa/ => same as .rot(1)
(qw/aa bb cc dd ee/).roll(2) # qw/dd ee aa bb cc/ => same as .rot(-2)
(qw/aa bb cc dd ee/).roll() # qw/ee aa bb cc dd/ => same as .roll(1)
...
etc.
Also I wonder if one will be able to push(), pop(), etc. array slices as
well whole arrays. A' la
my @a=qw/aa bb cc dd ee/;
my $s=pop @a[0..2]; # or [0,2] or just [0] for that matters!
# $s='cc';
# @a=qw/aa bb dd ee/; => same as what I can do with slice()
Not terribly necessary, but indeed consistent IMHO.

you'll see that it shouldn't be so. AND, the writting as usuall is
fantastic incompetent. To illustrate, i quote:
