Well, I went to 256-bit short vectors as a permanent part of the
architecture, with long vectors as the next step.

But what about crypto assist instructions, as another example?

However, I think I will adjust this feature. You comlained I used up
too much of my opcode space, so I demonstrated that Concertina II had
the potential to have... a _lot_ of opcode space, even to ludicrous
lengths.

Now that I think I can finally wrap up Concertina II, having found how
to achieve its goals as best as possible, I can go on to Concertina
III... and, given your anguished pleas, I _will_ give up on block
structure for the next iteration.

In order to do that, though, it will have to be CISC, not RISC...
banks of 8 registes, sort of like Concertina I, but much less messy.
