      Fix issue #98. · e17ac4ad
      Robbert Krebbers authored
      We used to normalize the goal, and then checked whether it was of
      a certain shape. Since `uPred_valid P` normalized to `True ⊢ P`,
      there was no way of making a distinction between the two, hence
      `True ⊢ P` was treated as `uPred_valid P`.
      
      In this commit, I use type classes to check whether the goal is of
      a certain shape. Since we declared `uPred_valid` as `Typeclasses
      Opaque`, we can now make a distinction between `True ⊢ P` and
      `uPred_valid P`.

      Make nclose an explicit coercion. · 274209c2
      Robbert Krebbers authored
      We do this by introducing a type class UpClose with notation ↑.
      
      The reason for this change is as follows: since `nclose : namespace
      → coPset` is declared as a coercion, the notation `nclose N ⊆ E` was
      pretty printed as `N ⊆ E`. However, `N ⊆ E` could not be typechecked
      because type checking goes from left to right, and as such would look
      for an instance `SubsetEq namespace`, which causes the right hand side
      to be ill-typed.

      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.
