The C<bindAsEventListener()> method is added to the core Function class, providing the ability to create a closure over a method that can be bound to an event handler.

  var obj = new SomeClass();

  var closure = obj.someMethod.bindAsEventListener( this );

  element.onClick = closure;

=head1 CAVEATS

Modifying the prototype of core Javascript classes should be avoided, if possible. By doing this, you are modifying B<ALL> objects of this class, regardless of when they were instantiated or by whom, For some classes, such as Number and String, this includes primitives. This can lead to surprising effects and action-at-a-distance.

You have been warned.
