P1788,

Before voting begins, a few summary points:

   -- As was shown, the single sticky bit in Motion 15 is not enough to 
reliably propagate exceptional information through all computations... at 
least one additional sticky bit of history would be required.

   -- Tetrits with bool_set semantics can also easily separate "current 
operation" and "history," if this is required, by using a total of 4-bits 
(two for "current operation" and two for "history").

   -- The proposed octigit definitions no longer give us a conceptual model 
to reliably distinguish between NaI and Empty.

   -- Tetrits don't require hardware interlocks, either.

Power to the people.
