RIGHT_AND_EXISTS_CONV
Conv.RIGHT_AND_EXISTS_CONV : conv
Moves an existential quantification of the right conjunct outwards through a conjunction.
When applied to a term of the form P /\ (?x.Q), the conversion
RIGHT_AND_EXISTS_CONV returns the theorem:
|- P /\ (?x.Q) = (?x'. P /\ (Q[x'/x]))
where x' is a primed variant of x that does not appear free in the
input term.
Failure
Fails if applied to a term not of the form P /\ (?x.Q).
