     Importantly, the user must specify how they intend to use the op, by
     specifying the direction of the portref type that this op is generated with.
     If the request port is to be read from, the type must be `!ibis.portref<out T>`
     and if the port is to be written to, the type must be `!ibis.portref<in T>`.
     This is to ensure that the usage is reflected in the get_port type which in
     turn is used by the tunneling passes to create the proper ports through the

     This implies that the portref direction of the get_port op is independent of
