https://github.com/leanprover/lean/pull/1438#discussion_r105007325

@digama0 With this commit, the original `array_list.write` will also
perform a destructive update when the reference counter for `l` is 1.

```lean def write {α} (l : array_list α) : fin l^.length → α → array_list α :=
λ ⟨n, h⟩ v, { l with data := l^.data^.write ⟨n, l^.lt_capacity h⟩ h v }
```

7ac6b14d2a chore(library/init/data/int/basic): use abstract when transfering in an instance declaration
@johoelzl I'm using `abstract` tactic because instances are
automatically marked as [reducible], and they will be unfolded when
solving unification constraints. This cannot be avoided since we need to
solve unification constraints such as

      int.has_add =?= comm_ring.to_has_add int.comm_ring

The `abstract tac` tactic creates an auxiliary lemma to store the proof
generated by `tac`. If we use `print int.comm_ring` we can see that
the definition is much smaller. The proofs are irrelevant. So, this has
no drawbacks, and gives us a good performance boost.

This commit introduces the transfer method. As application it is
used it to prove that the integers form a commutative ring.

0c6108ce7a chore(library/init/data/quot): use Sort instead of Type
Remark: The kernel was already using Sort. So, the limitation was
artificial. Moreover, it may seem unnecessary to have quotients of
proofs in a proof irrelevant system, but this is useful for proving
a more general funext lemma. This more general version is needed in
the new tested contributed by @digama0.
