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 →.

Based on an idea and WIP commits of JH. Jourdan: the core of a CMRA A is now a partial function A → option A. TODO: define sum CMRA TODO: remove one shot CMRA and define it in terms of sum

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.

For consistency's sake.

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

This way we avoid many oneoff indexes and no longer need special cases for index 0 in many definitions. For example, the definition of the distance relation on option and excl has become much easier. Also, uPreds no longer need to hold at index 0. In order to make this change possible, we had to change the notions of "contractive functions" and "chains" slightly. Thanks to Aleš Bizjak and Amin Timany for suggesting this change and to help with the proofs.

This way we can more easily state lemmas for concrete languages for arbitrary global functors.

Instead, we have just a construction to create a CMRA from a RA. This construction is also slightly generalized, it now works for RAs over any timeless COFE instead of just the discrete COFE. Also: * Put tactics and big_ops for CMRAs in a separate file. * Valid is now a derived notion (as the limit of validN), so it does not have to be defined by hand for each CMRA. Todo: Make the constructions DRA > CMRA and RA > CMRA more uniform.
