I've got some ideas about that, but the first step is to deprecate the
"feature" that allows you to write "f(int a[])" for "f(int *a)".  (I refer
here to the declaration of the function, not its call.)  In my mind, since
arrays may not currently be passed as arguments, the declaration is an error,
and the compiler is "politely" figuring out what you must have *meant*.  As
has already been pointed out, "sizeof(a)" gives you "sizeof(int *)" in this
context, so the apparent acceptance of the declaration tends to be confusing.
