WARNING! WARNING! DANGER WILL ROBINSON!

Note that void pointers are assignment compatible with DATA pointers of
all types. CODE pointers are not necessarily assignment compatible, and
indeed on some architectures have different physical format and sizes;
function pointers may require MORE STORAGE than data pointers, and hence
not fit in a void pointer.
