      Make specialization patterns for persistent premises more uniform. · 65bfa071
      Robbert Krebbers authored
      Changes:
      - We no longer have a different syntax for specializing a term H : P -★ Q whose
        range P or domain Q is persistent. There is just one syntax, and the system
        automatically determines whether either P or Q is persistent.
      - While specializing a term, always modalities are automatically stripped. This
        gets rid of the specialization pattern !.
      - Make the syntax of specialization patterns more consistent. The syntax for
        generating a goal is [goal_spec] where goal_spec is one of the following:
      
          H1 .. Hn : generate a goal using hypotheses H1 .. Hn
         -H1 .. Hn : generate a goal using all hypotheses but H1 .. Hn
                 # : generate a goal for the premise in which all hypotheses can be
                     used. This is only allowed when specializing H : P -★ Q where
                     either P or Q is persistent.
                 % : generate a goal for a pure premise.

      Improve iFrame tactic · 43d45c6b

      - It can now also frame under later.
      - Better treatment of evars, it now won't end up in loops whenever the goal
        involves sub-formulas ?P and it trying to apply all framing rules eagerly.
      - It no longer delta expands while framing.
      - Better clean up of True sub-formulas after a successful frame. For example,
        framing "P" in "▷ ▷ P ★ Q" yields just "Q" instead of "▷ True ★ Q" or so.
