The `Eq.symm` of a `rfl` theorem is a `rfl` theorem, the application
of `rfl` theorem too.

4848ad4869 feat: implement autoUnfold at simp 
Right now, it only supports the following kind of definitions
- Recursive definitions that support smart unfolding.
- Non-recursive definitions where the body is a match-expression. This
kind of definition is only unfolded if the match can be reduced.

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.
