After more discussions and contemplations, I think it would also be
useful to add a listener to send notifications when EL resolutions take
place. So I am thinking of addition a method to the ELListener
propertyResolved(ELContext, Object base, Object property);
It may also be necessary to add to ELContext another method
setPropertyResolved(boolean resolved, Object base, Object property);
to pass base and property to the listeners.
Comments? I'll work out the details and report back later.
