( #3333=superdoc: print w/replies, xml ) Need Help??
Oh thanks that's indeed interesting, Perl core finally allowing aliasing of lexicals! :)

... not sure if it solves the all issues yet...

But you know these new possibilities deserve a proper thread ...

update
hmm ... coupling is broken after assigning a new ref

use 5.22.0; use feature qw/say refaliasing/; no warnings "experimental::refaliasing"; \my @a = my $a = [666]; say "noref: $a[0], ref: $a->[0], list: @a"; $a = [42]; say "noref: $a[0], ref: $a->[0], list: @a";
-->
noref: 666, ref: 666, list: 666 noref: 666, ref: 42, list: 666

update

at least passing arrays to arrays is possible now

use 5.22.0; use feature qw/say refaliasing/; no warnings "experimental::refaliasing"; my @a = (666,42); test (\@a,\@a); sub test { (\my @sub, my $ref) = @_; say "noref: $sub[0], ref: $ref->[0], list: @sub"; }
-->
noref: 666, ref: 666, list: 666 42

well the syntax when passing more than one argument is not very elegant, see duplicated my ... but at least it's consistent.
