YES. When we want to clean up the code, it can't be right to push the
dirty tricks around long enough until we find a corner the current
compiler does not inspect. Which place would be nice? Below the sofa?
under the carpet? Behind the door? No this won't work. Ah, look, let's
hide it behind a (void *) cast. Urgh. This is ugly. :-)

For all: no offense meant.
