    $$foo is not a shorthand for $foo->.

    >perl -E"$foo=\'foo'; say $$foo;" foo >perl -E"$foo=\'foo'; say $foo->;" syntax error at -e line 1, near "->;" Execution of -e aborted due to compilation errors.

    You're probably thinking of the equivalency of $$foo[...] and $foo->[...] and of $$foo{...} and $foo->{...}, but that's already mentioned.
