What happens if you try
Node.spawn(:"suv@127.0.0.1", Kernel, :send, [caller, {:response, 1+2}])
?
Re erl_eval in #Function<43.125776118/0 in :erl_eval.expr/6> I think it just means that the anonymous function was defined in IEx. It might or might not mean that erl_eval is the problem. It might as well be Kernel.send/1, if that module / function were updated between 1.15.5 and 1.15.8, which they probably were, at least in “version”.
