      Make the types of the finite map type classes more specific. · 20b4ae55
      Robbert Krebbers authored
      This makes type checking more directed, and somewhat more predictable.
      On the downside, it makes it impossible to declare the singleton on
      lists as an instance of SingletonM and the insert and alter operations
      on functions as instances of Alter and Insert. However, these were not
      used often anyway.

      CMRAs with partial cores. · cfb00b3e
      Robbert Krebbers authored
      Based on an idea and WIP commits of J-H. Jourdan: the core of a CMRA
      A is now a partial function A → option A.

      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.
