I’m looking for a short for loop to sum two vectors of different lengths as in the following MWE. In general `y` could be longer, shorter than `x` or equal to it in length.
```julia
julia> x = [1, 2, 3, 4]
4-element Vector{Int64}:
1
2
3
4
julia> y = [5, 6]
2-element Vector{Int64}:
5
6
julia> sum(i + j for (i, j) in (x, y))
14
```
it stops after considering the two elements of `y` and returns `14` as result. is there a way to make the loop continue after finishing `y`, so that the result would be `21`?

```julia
julia> sum(x) + sum(y)
21
```

`sum(x) + sum(y)`
