      Implement substitution by reification. · dd543f95
      Robbert Krebbers authored
      We reify to a representation of expressions that includes an explicit
      constructor for closed terms. Substitution can then be implemented as
      the identify, which enables us to perform it using computation.

      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.

      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.

      Remove wp_X> tactics and improve wp_finish. · eab6c6c4
      Robbert Krebbers authored
      Since strip_later is doing a good job stripping laters in the conclusion,
      these tactics are thus no longer needed. Also, wp_finish now properly
      converts the result in a primitive viewshift in case it is not a weakestpre.
