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).
