That'd have to be more like:

    sub check_it_out (&idx is rw, &val is rw) {
        idx() = 0;
        val() = 7;
    }

Note that that's almost a macro definition:

    sub check_it_out is inline (&idx is rw, &val is rw) {
        idx() = 0;
        val() = 7;
    }

That might not be enough info, though.  May need to declare
the parameters to have no arguments:

    sub check_it_out is inline (&idx() is rw, &val() is rw) {
        idx() = 0;
        val() = 7;
    }
