strip_existsboolSyntax.strip_exists : term -> term list * term
Iteratively breaks apart existential quantifications.
If M has the structure ?x1 ... xn. t then
strip_exists M returns ([x1,...,xn],t). Note
that
strip_exists(list_mk_exists(["x1";...;"xn"],"t"))
will not return ([x1,...,xn],t) if t is an
existential quantification.
Never fails.
