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.

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.

feat: in an inductive family the longest fixed prefix of indices is now promoted to parameters
...
This modification is relevant for fixing regressions on recent changes
to the auto implicit behavior for inductive families.
The following declarations are now accepted:
```lean
inductive HasType : Fin n → Vector Ty n → Ty → Type where
| stop : HasType 0 (ty :: ctx) ty
| pop : HasType k ctx ty → HasType k.succ (u :: ctx) ty
inductive Sublist : List α → List α → Prop
| slnil : Sublist [] []
| cons l₁ l₂ a : Sublist l₁ l₂ → Sublist l₁ (a :: l₂)
| cons2 l₁ l₂ a : Sublist l₁ l₂ → Sublist (a :: l₁) (a :: l₂)
inductive Lst : Type u → Type u
| nil : Lst α
| cons : α → Lst α → Lst α
```
TODO: universe inference for `inductive` should be improved. The
current approach is not good enough when we have auto implicits.
TODO: allow implicit fixed indices that do not depend on indices that
cannot be moved to become parameters.
