Subject: -new: recursive costs system, useful to determine automatically  when
 to evaluate arguments and when to meta-unroll. -use it in Product to
 determine when to eval args. not yet used  to determine when to unroll. for
 now, not used anywhere else but  that'll follow. -fix badness of my last
 commit
