68629b2e5f feat(library/init/category/transformers): disable instance has_monad_lift_t ==> has_coe
It produces non-termination because it triggers sub-problems of the
form (has_monad_lift_t t ?M), and this kind of sub-problem is bad
for the transitive closure rule:

instance has_monad_lift_t_trans (m n o) [has_monad_lift n o] [has_monad_lift_t m n] : has_monad_lift_t m o

The trick above only behaves well for synthesis subproblems that do not
contain sub-variables.

Note that the sub-problem (has_monad_lift_t t ?M) is created by a
similar rule used at has_coe_t.

instance {a : Type u₁} {b : Type u₂} {c : Type u₃} [has_coe a b] [has_coe_t b c] : has_coe_t a c
AND
instance {m n} [has_monad_lift_t m n] {α} : has_coe (m α) (n α) :=

We workaround the issue by disabling

  instance {m n} [has_monad_lift_t m n] {α} : has_coe (m α) (n α)

and adding instances of it. Example:

  meta instance (α : Type) : has_coe (tactic α) (solver α) := ...
  meta instance (α : Type) : has_coe (tactic α) (prover α) := ...
  meta instance (α : Type) : has_coe (tactic α) (smt_tactic α) := ...

66bc3c796a feat(frontends/lean/elaborator): add extra coercion resolution rule for monads
We also removed the notation (♯tac) since it is not needed anymore.

@gebner, the comment at elaborator.cpp explains why you had to use the ♯
notation. The workaround is a little bit hackish, but I think it is
worth it. We will use monad lifts in many different places.

b86494f0d4 feat(library/tactic): add destruct tactic that is similar to cases, but does not use revert/intro/clear
This tactic is useful for building more complex tactics using ematch and
cc because it does not invalidate cc_state nor ematch_state.
