With a tied array it should be feasable to always access @$ref. ( well quite slow but good enough for a showcase.)

These variables are scoped and easy to identify (at least lexicals) you can just replace every @arr with @$are at compile time or in a macro substitution.

I doubt that's documented or guaranteed behavior.

At least with stash variables you are free to change the reference by aliasing.

Just try *a=\@b; and see what \@a returns. :)

update

furthermore this allows changing the underlying reference.

use 5.22.0;
use feature qw/say refaliasing/;
no warnings "experimental::refaliasing";

my @a=(1,2,3);
my @b=(3,2,1);

say \@a;

\@a=\@b;

say \@a;
