Thu, 14 Apr 2011 11:24:05 +0200 blanchet correctly handle TFrees that occur in (local) facts -- Metis did the right thing here but Sledgehammer was incorrectly generating spurious preconditions such as "dense_linorder(t_a)"

Thu, 14 Apr 2011 11:24:05 +0200 blanchet improve on 0b05cc14c2cb: make sure that a literal variable "?foo" isn't accidentally renamed "?Q", which might be enough to confuse the new Skolemizer (cf. "Clausify.thy" example)

Thu, 14 Apr 2011 11:24:05 +0200 blanchet "unify_first_prem_with_concl" (cf. 9ceb585c097a) sometimes throws an exception, but it is very rarely needed -- catch the exception for now
Thu, 14 Apr 2011 11:24:05 +0200 blanchet compile
Thu, 14 Apr 2011 11:24:05 +0200 blanchet handle case where the same Skolem name is given different types in different subgoals in the new Skolemizer (this can happen if several type-instances of the same fact are needed by Metis, cf. example in "Clausify.thy") -- the solution reintroduces old code removed in a6725f293377

Thu, 14 Apr 2011 11:24:04 +0200 blanchet use old Skolemizer for Metis call that requires high unification bound (around 100) with the new Skolemizer
Thu, 14 Apr 2011 11:24:04 +0200 blanchet try to repair out-of-sync situations in Metis
Thu, 14 Apr 2011 11:24:04 +0200 blanchet handle Vampire [predicate definition introduction] steps the same way as missing proof, since such steps do not report which axioms were used

Fri, 08 Apr 2011 19:04:08 +0200 boehmes use unification instead of matching to find proper assertions (which might not match original assumptions due to lambda-lifting and introduction of fresh variables)
Fri, 08 Apr 2011 19:04:08 +0200 boehmes fixed eta-expansion: use correct order to apply new bound variables
Fri, 08 Apr 2011 19:04:08 +0200 boehmes check if negating the goal is possible (avoids CTERM exception for Pure propositions)

Fri, 08 Apr 2011 19:04:08 +0200 boehmes corrected order of steps in Z3 proof reconstruction for elimination of unused quantified variables: first try to eliminate unused variables, then skip over used variables
