list_mk_res_existsres_quanLib.list_mk_res_exists : ((term # term) list # term) -> term)
Iteratively constructs a restricted existential quantification.
list_mk_res_exists([("x1","P1");...;("xn","Pn")],"t")
returns "?x1::P1. ... ?xn::Pn. t".
Fails with list_mk_res_exists if the first terms
xi in the pairs are not a variable or if the second terms
Pi in the pairs and t are not of type
":bool" if the list is non-empty. If the list is empty the
type of t can be anything.
