At least as I understood Luke's points, the reason for the two interfaces
is not that the underlying hashes are different (though they can be and
are), but that with one interface set you stop when you see a NUL (the str
ones) and the other you don't. It's like why we have strcpy() and
memcpy(). :-)

Take care,
