That's cos you ask hard questions :o)

A good point.  Sounds annoying.  :o(

I think the plan is to support different levels of error reporting, so when
you build the class, you set an option to say what kind of errors you want.
So what you'd do then is say that you don't want errors if the node doesn't
exist and you'd be happy, and if you want it to complain, you can leave the
errors on.  So yeah, we are aiming for this too :o)
