      Extend specialization patterns. · 87a8a19c
      Robbert Krebbers authored
      - Support for a `//` modifier to close the goal using `done`.
      - Support for framing in the `[#]` specialization pattern for
        persistent premises, i.e. `[# $H1 $H2]`
      - Add new "auto framing patterns" `[$]`, `[# $]` and `>[$]` that
        will try to solve the premise by framing. Hypothesis that are
        not framed are carried over to the next goal.

      Make iSpecialize work with coercions. · f1b30a2e
      Robbert Krebbers authored
      For example, when having `"H" : ∀ x : Z, P x`, using
      `iSpecialize ("H" $! (0:nat))` now works. We do this by first
      resolving the `IntoForall` type class, and then instantiating
      the quantifier.

      Improve `iSpecialize ("H" $! x1 .. xn)`. · 9ea6fa45
      Robbert Krebbers authored
      Instead of doing all the instantiations by invoking a single type
      class search, it now performs the instantiations by invoking
      individual type class searches. This a.) gives better error messages
      and b.) works when `xj` depends on `xi`.

      Improve `iIntros "_"`. · 211c2363
      Robbert Krebbers authored
      In the following ways:
      - When having `P → Q` it will now also work when the spatial context
        is non-empty.
      - When having `∀ x : A, Q` it will now do an `iIntros (_)`.

      Use symbol ∗ for separating conjunction. · cc31476d
      Robbert Krebbers authored
      The old choice for ★ was a arbitrary: the precedence of the ASCII asterisk *
      was fixed at a wrong level in Coq, so we had to pick another symbol. The ★ was
      a random choice from a unicode chart.
      
      The new symbol ∗ (as proposed by David Swasey) corresponds better to
      conventional practise and matches the symbol we use on paper.

      Generalize update tactics into iMod and iModIntro for modalities. · fc30ca08
      Robbert Krebbers authored
      There are now two proof mode tactics for dealing with modalities:
      
      - `iModIntro` : introduction of a modality
      - `iMod pm_trm as (x1 ... xn) "ipat"` : eliminate a modality
      
      The behavior of these tactics can be controlled by instances of the `IntroModal`
      and `ElimModal` type class. We have declared instances for later, except 0,
      basic updates and fancy updates. The tactic `iMod` is flexible enough that it
      can also eliminate an updates around a weakest pre, and so forth.
      
      The corresponding introduction patterns of these tactics are `!>` and `>`.
      
      These tactics replace the tactics `iUpdIntro`, `iUpd` and `iTimeless`.
      
      Source of backwards incompatability: the introduction pattern `!>` is used for
      introduction of arbitrary modalities. It used to introduce laters by stripping
      of a later of each hypotheses.
