I have a function (called form within an outer function) that I want to take a tuple of vectors of n integers. n is fixed for a given run of the outer function. How would I set this up?

```
function inner_func1(n ::Int64)
return Tuple([[1,2,3] for i in 1:n])
end
function inner_func2(y ::Tuple{Vector{Int64}})
return y[end]
end
function main_func(n)
y = inner_func1(n)
z = inner_func2(y)
end
main_func(3)
```

gives

```
