Output of functions

Dear users,
I have the following function:

function Test(u,v,w)
    x = sum(v)
    y = prod(v)
    z = u .+ v 
    return (x,y,z)
end

But,if I want only the first, or only the second or only third output, how can I do it?
For example, I my mind, the command

x = Test([1,2],[2,3],[3,4])

must return only the value of x, but return

(5,6,[3,5])

Anyone could help me please?

x, = Test([1,2],[2,3],[3,4])
Note the comma (after the x).

           return (x,y,z)
       end
Test (generic function with 1 method)

julia> x = Test([1,2],[2,3],[3,4])[1]
5

julia> y = Test([1,2],[2,3],[3,4])[2]
6

julia> z = Test([1,2],[2,3],[3,4])[3]
2-element Array{Int64,1}:

It was a type.

Ok!
I understood!
Thank you so much!

I actually didn’t know you could destructure like that. I sat here searching for like 30 seconds trying to figure out what comma you were talking about before I spotted it. For what it’s worth, even knowing that such destructuring is possible I find x, _, _ = Test(...) far more readable.
