This is where things can get messy.  Let's say you need to store a
character in a variable.  Usual practice is to use VARIABLE for this
because there's nothing conveniently smaller.  This leads to use
of @ ! in Forth code to handle characters which is an obvious type
mismatch.  Worse still if you forget and use C@ because then
your code is no longer endian portable.  Ideally Forth would come
with CVARIABLE as standard to encourage use of appropriately
typed operators but it never happened.
