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).
