- 'induct' may now use elim-style induction rules without chaining
facts, using ``missing'' premises from the goal state; this allows
rules stemming from inductive sets to be applied in unstructured
scripts, while still benefitting from proper handling of non-atomic
statements; NB: major inductive premises need to be put first, all the
rest of the goal is passed through the induction;
