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 →.

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.

That way, we do not have useless type annotations of the form "v : language.val heap_lang" cluttering about any goal. Note, that we could decide to eta expand everywhere (as we do for ∀ and ∃), and use the notation "WP e {{ Q }}" for "wp e ⊤ (λ _, Q)".

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.

* Put level of the triple at 20, so we can write things like ▷ {{ P }} e @ E {{ Φ }} without parentheses. * Use high levels for P, e and Φ. * Allow @ E to be omitted in case E = ⊤.

This avoids ambiguity with P and Q that we were using before for both uPreds/iProps and indexed uPreds/iProps.

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.
