 When I try to use a proc for a notification callback instead of a method,
 when the callback is made I am given the class object instead of the
 instance of the object.

 This example should work, but will not because when callback is called, it
 will be given the NSDictionary class constant instead of an instance of an
 NSDIctionary like I was supposed to get:

  framework 'Cocoa'

        callback = Proc.new { |notif| puts notif.userInfo.inspect }

        workspace = NSWorkspace.sharedWorkspace

        workspace.notificationCenter.addObserver callback,
                                        selector:'call:',
 name:NSWorkspaceDidLaunchApplicationNotification,
                                          object:nil

        workspace.launchAppWithBundleIdentifier 'com.apple.mail',
                                        options:NSWorkspaceLaunchAsync,
                 additionalEventParamDescriptor:nil,
                               launchIdentifier:nil

        NSRunLoop.currentRunLoop.runUntilDate( Time.now + 5 )
