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. :)
furthermore this allows changing the underlying reference.
