      Tweak the algebraic hierarchy. · a3d0a338
      Robbert Krebbers authored
      - 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.

      Merge iAssert and iPvsAssert. · e965b669
      Robbert Krebbers authored
      To do so, we have introduced the specialization patterns:
      
        =>[H1 .. Hn] and =>[-H1 .. Hn]
      
      That generate a goal in which the view shift is preserved. These specialization
      patterns can also be used for e.g. iApply.
      
      Note that this machinery is not tied to primitive view shifts, and works for
      various kinds of goal (as captured by the ToAssert type class, which describes
      how to transform the asserted goal based on the main goal).
      
      TODO: change the name of these specialization patterns to reflect this
      generality.

      Make specialization patterns for persistent premises more uniform. · 65bfa071
      Robbert Krebbers authored
      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.

      Improve iFrame tactic · 43d45c6b
      Robbert Krebbers authored
      - It can now also frame under later.
      - Better treatment of evars, it now won't end up in loops whenever the goal
        involves sub-formulas ?P and it trying to apply all framing rules eagerly.
      - It no longer delta expands while framing.
      - Better clean up of True sub-formulas after a successful frame. For example,
        framing "P" in "▷ ▷ P ★ Q" yields just "Q" instead of "▷ True ★ Q" or so.
