Hi. Recently I've experienced a bit odd behavior of schematic_lemma. Let's consider this minimal example: schematic_lemma surprise: "?A ⟹ ?B ⟹ ?C" proof - fix a1 :: 'a fix a2 :: 'a fix A :: "'a set" show "a1 ∈ A ⟹ a2 ∈ A ⟹ a1 = a1 ∧ a2 = a2" by auto qed Then what I get as a lemma surprise is the following theorem: ?a1.0 ∈ ?A ⟹ ?B ⟹ ?a1.0 = ?a1.0 ∧ ?a1.0 = ?a1.0
