Uhm... no, it's not.  The syntax

	E1[E2]

works for pointers as well as arrays.  The normal use is

	ArrayName [ expr ];

Now, since array names are converted to pointers, we get

	(ArrayName_as_Pointer) [ expr ];

which is the same as

	*((ArrayName_as_Pointer) + (expr));

Where's the conflict?  Or don't people understand what was being said?  (I opt
for the latter, actually, but I tend to give novices one break 8-).)
