Pack without Pack

Int, float, and list are all (normally hidden) message selectors that are assumed whenever Max encounters a message that consists of (respectively) a single int, a single float, or a multi-item message that starts with a number. Similarly, typing a single int, a single float, or any multi-item list that starts with a number directly into an object box assumes an object of type int (or i), float (or f), or list (or pack).

Stack overflow

Recursion, feedback loops, and unlimited untimed (as fast as possible) loops are not feasible in Max. In effect, you’d be asking Max to do an unlimited number of things all at the same time. Its scheduler (its internal “to-do” list) would get filled and it would be unable to do anything more. In computer lingo, its “stack” (its inbox of tasks to do) would overflow.
