moo? where did this come from, ha ha ok right michael i think i forgot to
put fcmp on #48 ay no it is there

frickin fantastic.  it passes the formal proof, right?

i am just trying to do gt dynamic partitioned

michael if you want something a bit challenging to do, could you see if you
can optimise the part_cmp eq.py code?
