Correct chasing of type variable instantiations during type unification. The following theory should not raise exception TERM: constdefs somepredicate :: "(('b => 'b) => ('a => 'a)) => 'a => 'b => bool" "somepredicate upd v x == True" lemma somepredicate_idI: "somepredicate id (f v) v" by (simp add: somepredicate_def) lemma somepredicate_triv: "somepredicate upd v x ==> somepredicate upd v x" by assumption lemmas somepredicate_triv [OF somepredicate_idI] lemmas st' = somepredicate_triv[where v="h :: nat => bool"] lemmas st2 = st'[OF somepredicate_idI]
