Potentially ambiguous. What if $it->{$key} returns a blessed scalarref that overloads both @{} and %{}? Is the next step $it->{$key}[$idx] or $it->{$key}{$idx}?

    Good point. That's the drawback where edge-cases can add a lot of complexity.
    Perhaps throw an exception? Allow annotations on how to resolve (see below)? Implicit rules? — down the rabbit hole of smart-matching :(

    Example: Resolve overloaded @{} by using the standard notation as a hint like so?

    $it->@( $key [$idx] section $i some.doc method1() sub1(5) method2($x) +);
    It should be rarely needed.
