Hi hol-info, Quick question: is there a tactic for instantiating a nested existential based on a name? Example: for a goal such as ?x y z. ... y ... I want to use a tactic foo_tac `y` `5` and get: ?x z. ... 5 ... Is there such a foo_tac tactic? I suspect this functionality is there somewhere already. If not, then I'll implement it. Note: I don't need the advanced feature of being able to instantiate it with `x+z+1` where the variables refer to the other existentially quantified variables. Many thanks, Magnus |
