in reply to Why Closures?

As a simple example of a useful application of closures (and some interesting discussion) see my Setting up signal handlers for an object with access to $self snippet. In this case, you can use closures to store the current value of a variable ($self in this case) to provide later access to its current value without having to explicitly store it anywhere.
