Actually I'd go with plan B: We don't do that. If we're telling the
compiler that a parameter to one of our functions is constant, we
shouldn't then go and change it, even indirectly. Lying to the
compiler is a Bad Thing--it messes up optimizations. (And if the
compiler trusts the const-ness of things, potentially fatally)
Either parameters are const and we don't change them, or they're not
declared const.
