You're mistaken.  In fact, this even pre-dates the ANSI C standard.
I have a copy of K&R's classic C book from the very first printing.

It clearly says that if you have:

   int x [ 10 ] ;

...then x [ 5 ] is equivelent to *(x + 5).

That works even if 'x' is an array of structures or some other
strangely sized thing.

I know this is suprising - but the compiler really does multiply the '5'
by sizeof(int) before adding it onto x.

However, failure to adequately bracket these kinds of expressions is
such a horribly common error that I'd strongly advise people to continue
to use the [] syntax 'as nature intended'.
