And the "event" implicit object is set up by JSF to point to the
ValueChangeEvent (or more generally, to whatever FacesEvent we
happen to be delivering) just prior to invoking any listeners.
This seems like a perfectly reasonable solution to me, and doesn't
require any special handling of expected/actual parameter types in
the EL layer.
IMO this is a far superior solution, as it is also far easier
understand - adding implicit parameters is very confusing!
