Leonardo de Moura	8df7c7b02d	feat(kernel/type_checker): remove fallback that expands opaque definitions in the type checker ... We should not rely on this feature. It can be quite expensive. We invoke is_convertible in several places, in particular, if we are using overloading. For example, the frontend uses is_convertible to check which overload should be used. Thus, it will make several calls such as is_convertible(num, Nat) If is_convertible starts unfolding opaque definitions, we would keep expanding num.

Leonardo de Moura	d4b08fcf96	feat(library/elaborator): be 'lazy' when normalizing terms in the elaborator ... Unification constraints of the form ctx |- ?m[inst:i v] == T and ctx |- (?m a1 ... an) == T are delayed by elaborator because the produce case-splits. On the other hand, the step that puts terms is head-normal form is eagerly applied. This is a bad idea for constraints like the two above. The elaborator will put T in head normal form before executing process_meta_app and process_meta_inst. This is just wasted work, and creates fully unfolded terms for solvers and provers. The new test demonstrates the problem. In this test, we mark several terms as non-opaque. Without this commit, the produced goal is a huge term.

Leonardo de Moura	e3dc552c39	fix(library/simplifier): nontermination ... The example tests/lua/simp1.lua demonstrates the issue. The higher-order matcher matches closed terms that are definitionally equal. So, given a definition definition a := 1 it will match 'a' with '1' since they are definitionally equal. Then, if we have a theorem theorem a_eq_1 : a = 1 as a rewrite rule, it was triggering the following infinite loop when simplifying the expression "a" a --> 1 --> 1 --> 1 ... The first simplification is expected. The other ones are not. The problem is that "1" is definitionally equal to "a", and they match. The rewrite_rule_set manager accepts the rule a --> 1 since the left-hand-side does not occur in the right-hand-side. To avoid this loop, we test if the new expression is not equal to the previous one. Signed-off-by: Leonardo de Moura <leonardo@microsoft.com>	2014-01-31 15:55:21 -08:00

Leonardo de Moura	8214c7add4	feat(library/elaborator): compensate the lack of eta-reduction (and eta-expanded normal forms) in the kernel normalizer ... Before this commit, the elaborator was solving constraints of the form ctx |- (?m x) == (f x) as ?m <- (fun x : A, f x) where A is the domain of f. In our kernel, the terms f and (fun x, f x) are not definitionally equal. So, the solution above is not the only one. Another possible solution is ?m <- f Depending of the circumstances we want ?m <- (fun x : A, f x) OR ?m <- f. For example, when Lean is elaborating the eta-theorem in kernel.lean, the first solution should be used: ?m <- (fun x : A, f x) When we are elaborating the axiom_of_choice theorem, we need to use the second one: ?m <- f Of course, we can always provide the parameters explicitly and bypass the elaborator. However, this goes against the idea that the elaborator can do mechanical steps for us. This commit addresses this issue by creating a case-split ?m <- (fun x : A, f x) OR ?m <- f Another solution is to implement eta-expanded normal forms in the Kernel. With this change, we were able to cleanup the following "hacks" in kernel.lean: @eps_ax A (nonempty_ex_intro H) P w Hw @axiom_of_choice A B P H where we had to explicitly provided the implicit arguments This commit also improves the imitation step for Pi-terms that are actually arrows.
