Re: [isabelle-dev] Datatypes Isatest failures

It doesn't seem like subst_tac had anything to do with it. I still have no idea about what made HOL-Proofs slower on at-poly-e beween September 13 and 14. The log reveals nothing special, except a truncation at the end. (while processing Predicate.thy). My personal inclination would be to

a) for lists: sum_list (← listsum), prod_list (← listprod) b) for multisets: Sum_mset (← msetsum), Prod_mset (← msetprod) c) for finite sets: Sum (← setsum), Prod (← setprod) I assume a) means Sum_list and Prod_list?! Why Sum and not Sum_set in c)? Is the intention that the canonical type
