2646f134d5 chore: add MonadBacktrack instance for ExceptT 2021-05-20 19:24:28 -07:00
Leonardo de Moura
030f53fa43 fix: closes #421 
The unifier used to implement the `cases` tactic should not discard
equations of the form `x = t` and `t = x` using proof irrelanvance.
The new test demonstrates the issue. The unifier was reaching the
state
```
x : Conw Con.nil
|- x = Conw.nilw -> x = Conw.nilw
```
and discarding the equality instead of substituting `x`
because `x` and `Conw.nilw` are definionally equal due to
proof irrelevance.

@javra Do you have more complicated examples that were being
affected by this issue?

2694e7798a refactor: add MonadBacktrack 
The new class specifies an interface for saving and restoring the
backtrackable part of the state.
This commit also fixes a few issues.

- `commitWhen` at `LevelDefEq` was defining a checkpoint for
  the `isDefEq` methods, and it affects how postponed universe
  constraints are handled. However, the name suggests it is
  similar to `commitWhenSome?`, and consequently it was used
  in other places that had nothing to do with `isDefEq`.
  So, I renamed it, and provided the generic `commitWhen` at the new
  `MonadBacktrack.lean` file.

- We were restoring more state then needed in a few places.
  For example, we were discarding all caches.

- At `SyntheticMVars.lean`, we were using the `Meta.commitWhenSome?`
  method which does not restore the `Term.State`.

7c2338546c feat: add pp.rawOnError 
@Kha after I enabled elaboration on syntactically incorrect terms, the
fallback is activated more often, and the raw term seems to have
little value for most users, and it is just scary.
Not sure whether the flag is a good idea, but it produces are more
user friendly output.

9a5f239513 refactor: remove Monad Option and Alternative Option 
We should use `OptionM` instead.
`Option` still implements `Functor` and `OrElse`.

@Kha I think this one is a good change, there is no real reason for
using the `!` suffix here.

into account.
