2020-07-211. Bugfix: implicits now properly name schematic variables. Fixes problems ↵Josh Chen1-7/+10
caused by variable name clashes. 2. reduce method now more principled: restricts to repeating on first subgoal. 3. An example declarative proof in Equivalence.thy.
2020-07-211. Type-checking/inference now more principled, and the implementation is ↵Josh Chen1-78/+69
better. 2. Changed most tactics to context tactics.
