I like it for the annotation we get.

	int fluff;
	if(fluff == 0)

This does not tell if fluff is an integer or a boolean (that is, what the
programmer intended to do -- not the 'int' the compiler sees).
If it had been if(!fluff), it would give a hint, but a lot of places also have
!x where x really is intended to be an integer (and should have been x==0 or
y==NULL resp.)
