      New definition of contractive. · 3caefaaa
      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. · bf6caa7f
      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.
