Sun, 30 Jun 2013 11:37:34 +0200 wenzelm backout dedd7952a62c: static "proofs" value within theory prevents later inferencing with different configuration;

Mon, 16 Mar 2009 23:52:30 +0100 wenzelm substantial speedup of assumption and elim-resolution: Logic.assum_problems refrains from eager application of parameters, discriminate via Term.could_unify before invoking full unification (assumes terms in beta-normal form, as do higher term net operations anyway);
