Can you give an example of what that actually > means? At first blush, this sets off warning bells in my head, I suppose because my notion of a lambda says that the lambda should not carry any baggage about the context it was created in. However, with further thought, I believe that binding the lambda's lexical scope to the place it was defined is: * Conducive to good coding (you will always be able to look outside the lambda to find out where the lexical variables are coming form) * Adds functionality, since anything you want to pass to the function via the callee's context can be passed via a parameter What would be neat, however, is the ability to rebind the lambda to another context. Also, I don't know how other languages do it (Python? Lisp?). -- Edward Z.
