The point Bill made recently about the stretch & tendon reflexes
taking care of intertial interacations between arm segments seems
to me to be *extremely* important, but it needs more backup. This
is because
(a) the actual function of these systems is a standing puzzle in the
motor control literature
(b) there is a body of opinion that think that feedforward will be
necessary to achieve efficient handling of such interactions
(I found a claim to this effect a reference Gavan gave me).
Part of the backup should be to give Little Man a shoulder-roll df;
another would be to check that the system is efficient in terms of
energy-use.
