EXISTS_CONSEQ_CONV : (conseq_conv -> conseq_conv)
STRUCTURE
SYNOPSIS
Applies a consequence conversion to the body of an existentially quantified term.
DESCRIPTION
If c is a consequence conversion that maps a term ``t x`` to a theorem |- t x = t' x, |- t' x ==> t x or |- t x ==> t' x, then EXISTS_CONSEQ_CONV c maps ``?x. t x`` to |- ?x. t x = ?x. t' x, |- ?x. t' x ==> ?x. t x or |- ?x. t x ==> ?x. t' x, respectively.
FAILURE
EXISTS_CONSEQ_CONV c t fails, if t is not an existentially quantified term or if c fails on the body of t.
