MK_PSELECT : (thm -> thm)
STRUCTURE
LIBRARY
pair
SYNOPSIS
Quantifies both sides of a universally quantified equational theorem with the choice quantifier.
DESCRIPTION
When applied to a theorem A |- !p. t1 = t2, the inference rule MK_PSELECT returns the theorem A |- (@x. t1) = (@x. t2).
       A |- !p. t1 = t2
   --------------------------  MK_PSELECT
    A |- (@p. t1) = (@p. t2)

FAILURE
Fails unless the theorem is a singly paired universally quantified equation.
