By using an argument filtering and a montonic ordering, at least one Dependency Pair of this SCC can be strictly oriented.

APP2(app2(forall, p), app2(app2(cons, x), xs)) -> APP2(p, x)
APP2(app2(forall, p), app2(app2(cons, x), xs)) -> APP2(app2(forall, p), xs)

APP2(app2(forsome, p), app2(app2(cons, x), xs)) -> APP2(app2(forsome, p), xs)
Used argument filtering: APP2(x1, x2)  =  x2
app2(x1, x2)  =  app2(x1, x2)
cons  =  cons
