be the same as
↔ . This is a fairly intrusive change, but at least makes notations more consistent, and often shorter because fewer parentheses are needed. Note that viewshifts already had the same precedence as →.

It used to be: (P ={E}=> Q) := (True ⊢ (P → ={E}=> Q)) Now it is: (P ={E}=> Q) := (P ⊢ ={E}=> Q)

Changes:  We no longer have a different syntax for specializing a term H : P ★ Q whose range P or domain Q is persistent. There is just one syntax, and the system automatically determines whether either P or Q is persistent.  While specializing a term, always modalities are automatically stripped. This gets rid of the specialization pattern !.  Make the syntax of specialization patterns more consistent. The syntax for generating a goal is [goal_spec] where goal_spec is one of the following: H1 .. Hn : generate a goal using hypotheses H1 .. Hn H1 .. Hn : generate a goal using all hypotheses but H1 .. Hn # : generate a goal for the premise in which all hypotheses can be used. This is only allowed when specializing H : P ★ Q where either P or Q is persistent. % : generate a goal for a pure premise.

iSpecialize and iDestruct. These tactics now all take an iTrm, which is a tuple consisting of a.) a lemma or name of a hypotheses b.) arguments to instantiate c.) a specialization pattern.

Thanks to Amin Timany for the suggestion.

Add both nonexpansive and contractive functors, and bundle them for the general Iris instance as well as the global functor construction This allows us to move the \later in the userdefined functor to any place we want. In particular, we can now have "\later (iProp > iProp)" in the ghost CMRA.

This cleans up some adhoc stuff and prepares for a generalization of saved propositions.

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

* These type classes bundle an identifier into the global CMRA with a proof that the identifier points to the correct CMRA. Bundling allows us to get rid of many arguments everywhere. * I have setup the type classes so that we no longer have to keep track of the global CMRA identifiers. These are implicit and resolved automatically. * For heap I am also bundling the name of the heap RA instance. There always should be at most one heap instance so this does not introduce ambiguities. * We now have a "maps to" notation!

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.

It is now slightly below implication. In order to do this, I had to change the notation from P ={E1,E2}=> Q to P >{E1,E2}=> Q because the prefer ={n is already used at level 70 for the distance of the metric.
