I dislike the notation because $ref is always referred to by $ref
everywhere ... except in this syntax.

In fact, I did want a "ref slice" a few days ago.  I had an array of
refs and I wanted the ID key out of all of them.  I wanted to do
    @arr->{ID}
but Perl doesn't allow that; I had to code it more verbosely as
    map { $_->{ID} } @arr
