Fri, 10 Jan 2014 23:42:18 +0100 wenzelm disable Thm.check_hyps for now, due to remaining problems with AFP/Datatype_Order_Generator and AFP/Psi_Calculi (because of HOL-Nominal 'equivariance');
Fri, 10 Jan 2014 21:37:28 +0100 wenzelm more elementary management of declared hyps, below structure Assumption;
Fri, 10 Jan 2014 16:20:06 +0100 wenzelm explicit check of background theory;

Sat, 23 Nov 2013 17:15:44 +0100 wenzelm more uniform / rigid checking of Goal.prove_common vs. Proof.conclude_goal -- NB: Goal.prove_common cannot check hyps right now, e.g. due to undeclared Simplifier prems;
