Great. Perhaps you'll discover a co-favourite CPU. ;-)

I expect to.  I looked at the ARM architecture when it first
came out, and was impressed with the simplicity and power.
Putting predicate bits on each instruction is certainly an
interesting approach, since it can be quite useful--but I
wondered at the time if it was useful enough to take up an
entire half of the coding space.

It reminded me of the way that older architectures used a bit
to flag indirect addresses, which is unthinkable in a world in
which address bits are precious and indirection is both slow
and uncommon.
