fix(library/init/meta/tactic): by_cases tactic
...
Before this commit, the `by_cases p` tactic would synthesize
`inst : decidable p` type class resolution, and then use the
`cases` tactic (dependent elimination). This would create
problems since occurrences of `inst` would be replaced with
`decidable.is_true h` in one branch, and `decidable.is_false h` in the
other. Where `h`s (we have two of them, one for each branch) are
fresh hypotheses introduced by the `cases` tactic.
For example, assume we have the term in our goal.
`@ite p inst A a b`
This term would become
`@ite p (decidable.is_true h) A a b` (in the first branch where `h : p`)
and
`@ite p (decidable.is_false h) A a b` (in the second where `h : not p`)
Now, suppose we try to executed the following tactic in the first branch
`rw [if_pos h]`
it will fail since `if_pos h` is actually `@if_pos p inst h`, and
we will not be able to unify
`@ite p (decidable.is_true h) A a b =?= @ite p inst ?A ?a ?b`
This commit workarounds this problem by applying cases on
`@decidable.em p inst : p or not p` instead of `inst : decidable p`.
Thus, the term `inst` is not replaced with `decidable.is_true h` and
`decidable.is_false h`.
The new test `tests/lean/run/simp_dif.lean` demonstrates the problem above.
