PGEN : (term -> thm -> thm)
STRUCTURE
LIBRARY
pair
SYNOPSIS
Generalizes the conclusion of a theorem.
DESCRIPTION
When applied to a paired structure of variables p and a theorem A |- t, the inference rule PGEN returns the theorem A |- !p. t, provided that no variable in p occurs free in the assumptions A. There is no compulsion that the variables of p should be free in t.
      A |- t
   ------------  PGEN "p"               [where p does not occur free in A]
    A |- !p. t

FAILURE
Fails if p is not a paired structure of variables, of if any variable in p is free in the assumptions.
