      Special proof mode class for adding a modality to a goal. · a63f256e
      Robbert Krebbers authored
      This used to be done by using `ElimModal` in backwards direction. Having
      a separate type class for this gets rid of some hacks:
      
      - Both `Hint Mode`s in forward and backwards direction for `ElimModal`.
      - Weird type class precedence hacks to make sure the right instance is picked.
        These were needed because using `ElimModal` in backwards direction caused
        ambiguity.

      Hide the proof mode entailment behind a definition. · 8574d1ea
      Robbert Krebbers authored
      This solves issue #100: the proof mode notation is sometimes not printed. As
      Ralf discovered, the problem is that there are two overlapping notations:
      
      ```coq
      Notation "P ⊢ Q" := (uPred_entails P Q).
      ```
      
      And the "proof mode" notation:
      
      ```
      Notation "Γ '--------------------------------------' □ Δ '--------------------------------------' ∗ Q" :=
        (of_envs (Envs Γ Δ) ⊢ Q%I).
      ```
      
      These two notations overlap, so, when having a "proof mode" goal of the shape
      `of_envs (Envs Γ Δ) ⊢ Q%I`, how do we know which notation is Coq going to pick
      for pretty printing this goal? As we have seen, this choice depends on the
      import order (since both notations appear in different files), and as such, Coq
      sometimes (unintendedly) uses the first notation instead of the latter.
      
      The idea of this commit is to wrap `of_envs (Envs Γ Δ) ⊢ Q%I` into a definition
      so that there is no ambiguity for the pretty printer anymore.

      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.
