I still don't see why this necessitates keyed variants of all the ops.
Couldn't we have a prepkeyed op which would return a specialized pmc
to use in the next op? Thus instead of
set P0, P1[P2]
we would have
prepkey P3, P1[P2]
set P0, p#
similarly
add P0[IO], P1
would become
prepkey

Yes, we could. But it would be in exchange for both speed (because

If either (or both) of somedata or otherdata isn't an array of PMCs,
there's going to be an awful lot of temporary PMC creation, which is a
waste.
