Yes but this still isn't an arguement for inter-session calling, and in addition, it also not an arguement against POE::Session->call(). Just because you /can/ make everything an event, doesn't neccesarily mean it should be given or even encouraged that you should make things which rely on a synchronous state and then shoe-horn them into an asynchronous framework.
Not everything needs to be an event, or so Rocco once told me.
True, but POE is nice because you /can/ make everything an event, if you so desire.
