Right, because it will also fail if you pass an invalid HWND to it, or do
something similar :).

Anyway, the point of the 'clipboard' example was that there are cases when
separation of assert()s from the mainline code leads to a code bloat, and
'VERIFY'-like macro is quite useful in such situations. I agree that the
example was controversial, though, something like '::FillRect' would
probably cause less disagreement about validity of the assertions there.
