It is doing much more than just dealing with ∈, it solves all kinds of goals involving set operations (including ≡ and ⊆).

simplify_equality => simplify_eq simplify_equality' => simplify_eq/= simplify_map_equality => simplify_map_eq simplify_map_equality' => simplify_map_eq/= simplify_option_equality => simplify_option_eq simplify_list_equality => simplify_list_eq f_equal' => f_equal/= The /= suffixes (meaning: do simpl) are inspired by ssreflect.

The tactic injection H as H is doing exactly that.

The singleton maps notation is now also more consistent with the insert <[_ := _]> _ notation for maps.

Also, make our redefinition of done more robust under different orders of Importing modules.

Since Coq 8.4 did not backtrack on eauto premises, we used to ensure that hints like Hint Extern 0 (?x ≡{_}≡ ?y) => reflexivity. were not used for goals involving evars by writing ?x ≡{_}≡ ?y instead of _ ≡{_}≡ _. This seems to be a legacy issue that no longer applies to Coq 8.5, so I have removed these restrictions making these hints thus more powerful.

This reverts commit 24fa20e5f8a2042caa19f1f6505102c5434cce54. Although these symmetric variants sometimes look "better", they are really annoying and should IMHO never be used: 1.) For lemmas there is now a choice between >= and <=. Since there is no longer a canonical choice, it is very easy to introduce a lot of inconsistencies in statements of lemmas. 2.) For automation the situation becomes annoying, you have to built in stuff for both >= and <=. That is very errorprone. 3.) For N and Z the notions x <= y and y >= x are not even convertible! That means that done/by does not solve x <= y if you have y >= x and if avoids you applying certain lemmas.
