That's a dangerous practice. It prevents you from using weak event
listeners -- because the only reference to your delegate function
object is the event listener itself, a weakly-referenced listener will
be garbage collected. Now have to manually remove your listener to
make sure your object is garbage collected -- but the only way to
remove event listeners is to pass the removeEventListener function a
reference to the function you want to remove... but you don't have
that reference!
If it's a one-time event, you can have the listener remove itself.
Your delegate function object can pass a reference to itself (using
arguments.callee) in to the "real" event listener function, which you
can use to remove the listener. In any other case, you'll have to
build a separate data structure (usually a Dictionary of Objects ->
Functions) to keep a reference available to your code.
