Comment (by Ulrich Eckhardt <ulrich.eckhardt@…>):

 Two things:
 1. That should be a static_cast, not a reinterpret_cast.
 2. I wonder if instead of casting a null to an according function pointer
 type, it would be possible to tell assert_arg explicitly like
 {{{assert_arg<void (*)(Pred)>(0, ...)}}} and then rely on the conversion
 of 0 to the according type to do the right thing.
