1. A : Type
2. Q : Sexpr(A)

Prop
3.

e:{e:Sexpr(A)| Q(e) }. Reverse(e)

Sexpr(A)
4. x1 : {e:Sexpr(A)| Q(e) }
5. x2 : {e:Sexpr(A)| Q(e) }

Reverse(Cons(x1;x2))

Sexpr(A)

By:	Compute Reverse(Cons(x1;x2)) * Cons(Reverse(x2);Reverse(x1)) THEN Analyze

Generated subgoals:

1 Reverse(x2) Sexpr(A)
1 step

2 Reverse(x1) Sexpr(A)
1 step
