2012-05-17 blanchet [Thu, 17 May 2012 13:36:23 +0200] rev 47939
added "Collect_cong" to cover extensionality of "Collect" (special cases of "ext" pass through the relevant filter)

2012-05-16 kuncar [Wed, 16 May 2012 19:20:19 +0200] rev 47938
remove the generation of a code certificate from the Quotient package (mainly from quotient_def), because it's in lift_definition now

2012-05-16 kuncar [Wed, 16 May 2012 19:17:20 +0200] rev 47937
generate abs_eq, use it as a code equation for total quotients; no_abs_code renamed to no_code; added no_code for quotient_type command

temporarily disable "ext" rule helpers until Metis supports them (and until they are properly evaluated)

2012-05-16 blanchet [Wed, 16 May 2012 18:16:51 +0200] rev 47934
lower skolem penalty to ensure that some useful facts with existentials, e.g. congruence of "setsum", eventually get picked up
src/HOL/Tools/Sledgehammer/sledgehammer_provers.ML

2012-05-16 blanchet [Wed, 16 May 2012 18:16:51 +0200] rev 47933
treat sets specially in relevance filter, as they used to, to avoid cluttering the problem with facts about Set.member and Collect

minor slice tweaking (swapped two slices to move polymorphic encoding up a bit)
