I think this would be a worthwhile innovation, and one that's as easy
to implement as sizeof. It wouldn't return a value, but would be used
anywhere a type could be used.

I realise this isn't quite what's meant here. An operator to return
some indication of the type of an object would be useful, but I'm not
sure what it'd return. A small integer? A structure? A pointer to a
structure? The "type" of a C object can be very complex... what would
it return for:

	struct {
		union uabc {
			struct {
				int a;
				int b;
			} ab;
			long c;
		} abc;
		union uabc *d;
		struct stat buf;
	} x;

But a typeof operator... wouldn't that be something...

#define SWAP(a,b) {typeof a tmp; tmp=a; a=b; b=tmp}
