      Tweak the lexer: In particular, improve notFollowedBy and friends · c250f93b
      Ian Lynagh authored
      We were hitting a problem when reading the LANGUAGE/OPTIONS pragmas
      from GHC.TypeLits, where the buffer ended "{-". The rules for the
      start-comment lexeme check that "{-" is not followed by "#", but the
      test returned False when there was no next character. Therefore we
      were lexing this as as an open-curly lexeme (only consuming the "{",
      and not reaching the end of the buffer),
      which meant the options parser think that it had reached the end of
      the options.
      
      Now we correctly lex as "{-".

      Fix the the pure unifier so that it unifies kinds · 6c3045b9
      Simon Peyton Jones authored
      When unifying two type variables we must unify their kinds.
      The pure *matcher* was doing so, but the pure *unifier* was not.
      This patch fixes Trac #6015, where an instance lookup was failing
      when it should have succeeded.
      
      I removed a bunch of code aimed at support sub-kinding. It's
      tricky, ad-hoc, and I don't think its necessary any more.
      Anything we can do to simplify the sub-kinding story is welcome!
