This PR adds the `try?` tactic. This is the first draft, but it can already solve examples such as: ```lean example (e : Expr) : e.simplify.eval σ = e.eval σ := by try? ``` in `grind_constProp.lean`. In the example above, it suggests: ```lean induction e using Expr.simplify.induct <;> grind? ``` In the same test file, we have ```lean example (σ₁ σ₂ : State) : σ₁.join σ₂ ≼ σ₂ := by try? ``` and the following suggestion is produced ```lean induction σ₁, σ₂ using State.join.induct <;> grind? ``` |
