      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.

      Remove Existing Class Is_true. · 94ecebcc
      Robbert Krebbers authored
      Having Is_true as a type class caused problems with rewrite: when the
      rewrited lemma has a premise of the shape Is_true, the rewrite tactic
      will complain that it cannot find a type class instance, instead
      of generating a goal for that premise.
