I agree with Dr. Andrews in part: we use the Greenhills C compiler here,
and it fries it's mind on:

	char a;
	int i = 2;

	a = i["Hello World"];

However I would have thought that any compiler that can't do for loops properly
is gonna die real fast. I personally do not use the a = i["..."]; form
ever, so that is not too much of a problem, but if I have to ditch for loops
I'll go out and buy another compiler.
