- Another bug in get_sort_family_of (sort-polymorphism of constants and
inductive types was not taken into account).
- Virtually extended tauto to
- support arbitrary-length disjunctions and conjunctions,
- support arbitrary complex forms of disjunctions and
conjunctions when in the contravariant of an implicative hypothesis,
- stick with the purely propositional fragment and not apply reflexivity.
This is virtual in the sense that it is not activated since it breaks
compatibility with the existing tauto.
- Modified the notion of conjunction and unit type used in hipattern in a
way that is closer to the intuitive meaning (forbid dependencies
between parameters in conjunction; forbid indices in unit types).
- Investigated how far "iff" could be turned into a direct inductive
definition; modified tauto.ml4 so that it works with the current and
the alternative definition.
- Fixed a bug in the error message from lookup_eliminator.
- Other minor changes.
