Hi Sylvain, Selector does no coercion and I have the same preference. Everything comes through as strings. Some dispatch strategies do entail coercion and it is a hurdle to making dispatchees portable but I don't seen the routing_args convention being adopted if there was a restriction on types. I agree with you that it would be nice for any dispatch tool that does coercion to make it easy to turn off. Maybe we should annotate the spec?
