50813429b8 fix: add expected type hint 
Other tactics (e.g., `simp_all`) may try to infer the type of the
proof, and `Nat.Linear.eq_of_toNormPoly_eq` has a messy resulting type.

272dd5533f chore: style use · instead of . for lambda dot notation 
We are considering removing `.` as an alternative for `·` in the
lambda dot notation (e.g., `(·+·)`).
Reasons:
- `.` is not a perfect replacement for `·` (e.g., `(·.insert ·)`)
- `.` is too overloaded: `(f.x)` and `(f .x)` and `(f . x)`. We want to keep the first two.

ca253c43e1 refactor: pattern elaboration 
We don't use the following hack anymore:
-  /- HACK: `fvarId` is not in the scope of `mvarId`
-     If this generates problems in the future, we should update the metavariable declarations. -/
-  assignExprMVar mvarId (mkFVar fvarId)

This hack was corrupting the `InfoTree`.
