Re: [isabelle] "blast" eliminates unrelated flex-flex pairs in Isabelle2013-1 and Isabelle2013-2.
You shouldn’t have to redo the proofs. If you are lucky, doing the proof in Isabelle2013 may give you a clue as to how the variables are being instantiated, so that you can add a constraint somewhere. And flex-flex constraints are very rare.
Do you really have 400k lines of Isabelle proof scripts? All of the Isabelle/HOL theories (including examples and libraries) are barely more than that.
