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.

  • Titles consisting of a single word are discouraged, and in most cases are disallowed outright.
  • Read Where should I post X? if you're not absolutely sure you're posting in the right place.
