It shouldn't take you more than a few seconds to honor my request, while it might take me hours to honor yours. The fundamental problem is that I won't even necessarily recognize what you're referring to, even if it's staring me in the face. There's a pretty good chance that what you think is code that depends upon the representation of null pointers is, in fact, not so dependent. Alternatively, it might be code that I incorrectly think has no such dependence - either way, I won't recognize it when I see it. However, if you would just identify the particular code you're talking about, which should only take you a few seconds, it might save me hours of possibly fruitless searching, and we can move on to the discussion of whether or not you're correct, and whether or not it was actually necessary to write such code.
