I would have to disagree with you here, since it is (or should be) 
widely known that _. is a wildcard match, and will match ANYTHING.  This 
behaviour is GOOD, when you just need to capture anything that is sent 
into a particular context, and parse it.  Sure, ruling out _. would be 
great for newbies, but some of us experienced folk use this for more 
than just numeric extensions - we actually determine, and work around 
some of the system extensions using this operator.
