The intropattern {H} also meant clear (both in ssreflect, and the logic part of the introduction pattern).

Concretely, when execution of any of the wp_ tactics does not yield another wp, it will make sure that a view shift is kept. This behavior was already partially there, but now it is hopefully more consistent.

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.

And make constants P for which we do not want of_val P to reduce Opaque.

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.

 It can now also frame under later.  Better treatment of evars, it now won't end up in loops whenever the goal involves subformulas ?P and it trying to apply all framing rules eagerly.  It no longer delta expands while framing.  Better clean up of True subformulas after a successful frame. For example, framing "P" in "▷ ▷ P ★ Q" yields just "Q" instead of "▷ True ★ Q" or so.

Par is now defined as an expression of type [∀ X, expr X] (instead of a value) and we prove that it is stable under weakening and substitution.

It is not a library; it does not contain code, but instead is a core part of heap_lang.

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.

Tactics like wp_proj should always solve all to_val sideconditions. The tactic wp_done is used to handle these in a uniform way.
