Streaming Expression: get the value of the array at the specified position

[Nazerke S]

Hi,

I am interested in getting the value of the array at the given index. For
example,

let(echo="b", a=array(1,2,3,4,5), b=getAt(a, 2))  should return 3.

Is there a way to get access an array's element by indexing?

Thanks!
