I interpreted Dwight's post as a 1-bit serial ALU operating on

As far as variable-length opcodes, again, that's a matter of opinion.
Many microcontrollers have variable length opcodes. with the
instruction packed into a fixed-length word.

Notice that Dwight is talking about variable numbers of *bits* in the
instruction (by which I think he means "op code"), and Tony and Eric
both appear to at elast wonder if that's what he means.
