      New definition of contractive. · 176a588c
      Robbert Krebbers authored
      Using this new definition we can express being contractive using a
      Proper. This has the following advantages:
      
      - It makes it easier to state that a function with multiple arguments
        is contractive (in all or some arguments).
      - A solve_contractive tactic can be implemented by extending the
        solve_proper tactic.

      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.
