I'm not sure I buy that reasoning.  You seem to be saying that since it's
not possible to detect all invalid addresses syntactically that the ability
to trap some syntactically (or more than currently trapped) is irrelevant.
I disagree.  I believe it's usually faster, simpler, and more reliable to
catch errors syntactically than relying on subsequent semantics.
