I've been wondering whether it would be possible to write programs that have most of their memory in 32 bits, so most pointers would be 32 bits.
Also, such program would have int as a 32 bit value unless specifically declared to be larger - we could write programs that use less memory, but still use more registers, and use 64bit pointers and values as necessary
