Their is a open question about the need to support
self modifying code
too. I personally don't think of that as important as the need for
conditional instructions which I do think need to be there before you
can really call it a computer.
Here's one way to look at it: with conditional branching, one can always
write a program to _emulate_ a machine with self-modifying code (if that's
what floats your boat, computing-wise) - because that's exactly what older,
simple microcoded machines (which don't, of course, have self-modifying code
- their programs are in ROM) do.
