Not actually true. I have a simple puzzle game running in iOS with mocl. Lisp does the Model+Controller part and the View is in ObjectiveC. Once the game is running I can change states like level-up&#x2F;down, etc. and the changes are reflected in real-time. I cannot change functions like in a true CL environment on the desktop, but I can definetly change global things to see if e.g. my flow works...
