Not quite, unfortunately.  Section 3.1.2.1.1 says:

"There are three kinds of variables: lexical variables, dynamic  
variables, and constant variables."

Now, I suppose one could argue whether this means "There are three,  
AND ONLY THREE, kinds of variables" or whether it means "There are AT  
LEAST three kinds of variables."  To my ear it sounds like an  
exhaustive enumeration, but reasonable people could disagree.

I would also like to draw everyone's attention once again to the  
following:

No one has commented on this yet one way or the other.  If you don't  
think this (or something like it) is the best solution I would really  
like to know what you think is wrong with it.
