How then to account for their behavior with "sizeof"?  I recommend
thinking of them not AS pointer constants, but as (almost) universally
CONVERTED TO pointer constants.  That accounts for their behavior
in sizeof, and even in multiply-dimensioned arrays (that is, if you
have an array of arrays, you have an array of... constants??? nah!).

So again... it's not that arrays ARE pointer constants, but that they
are CONVERTED TO pointer constants (almost always).  This seems to me
to be the least confusing way of thinking about it while using C.
