RIGHT_OR_EXISTS_CONV
Conv.RIGHT_OR_EXISTS_CONV : conv
Moves an existential quantification of the right disjunct outwards through a disjunction.
When applied to a term of the form P \/ (?x.Q), the conversion
RIGHT_OR_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).
