Constructor Details

#initialize(object, binding, host = '127.0.0.1', port = 7829) ⇒ Socket

Initializes with the object and binding that each new connection will get as Context. The binding is shared, so local variables will stay around. The benefit of this is that a socket based irb session is most probably used to debug a running application in development. In this scenario it could be beneficial to keep local vars in between sessions.

TODO see if that actually works out ok.
