Sorry; You're of course right.
I should been less specific and more useful and said, "But then you
lose the size of the array".
I've seen such things used in C++ like this:
template <typename T, size_t N>
size_t array_length(T (&)[N]) { return N; }
In place of sizeof(p)/sizeof(*p), in order to get a compilation
failure if a pointer is accidentally passed.
