Likewise, a domain literal can consist solely of the
square brackets.
so? there are lots of addresses which are valid syntax but
not valid because the domain is not defined or the IP
address (in the domain literal) does not exist or is not
assigned to a host.
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.
