This is more consistent with the definition of the extension order, which is also defined in terms of an existential.

This is inspired by ssr, and makes unification faster if it goes righttoleft. See https://sympa.inria.fr/sympa/arc/ssreflect/201311/msg00010.html

This way, we can use eapply instead of class_apply, which is used when the instances are defined using the Instance command. It seems that eapply is stronger as class_apply, and as such solves some issues when canonical structures have type class parameters, for example: Goal Op (option (dec_agree nat)). apply _. This failed, but is fixed by this commit.

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

 Make the carrier argument of the constructors for the canonical structures cofeT and cmraT explicit. This way we make sure the carrier is properly exposed, instead of some alias of the carrier.  Make derived constructions (such as discreteC and discreteR) notations instead of definitions. This is yet again to make sure that the carrier is properly exposed.  Turn DRA into a canonical structure (it used to be a type class). This fixes some issues, notably it fixes some broken rewrites in algebra/sts and it makes canonical structures work properly with dec_agree.

The only drawback is that we have to restrict iprod to finite types, but that is fine.

Thanks to Amin Timany for the suggestion.

So, only use the type class for contractive functors.

Ralf Jung authored
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.

Since functor instances are just used as combinators, there is really no need for functors that are not contractive.

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