It would be a fun exercise to construct a target platform to test all these 
whacky possibilities. Make the null pointer not be represented all zeros, 
have sizeof(double) == sizeof(char), sizeof(function pointer) != sizeof(data 
pointer), etc. 

BTW, type_traits also makes the assumption that sizeof(char) != 
sizeof(double). We could just change it to:

typedef char yes_type[2];
typedef char no_type[1];
