Shifting the range of iteration.

A:Type, f:(A

A), u:A, a,b:

, e:({a..b

}

A), k:

(Iter(f;u) i:{a..b

}. e(i)) = (Iter(f;u) j:{a+k..b+k

}. e(j-k))

By:	Guarding (a:<type>. <prop>) Auto

Generated subgoal:

1 1. A : Type
2. f : AAA
3. u : A
a,b:, e:({a..b}A), k:.
(Iter(f;u) i:{a..b}. e(i)) = (Iter(f;u) j:{a+k..b+k}. e(j-k))
