Automatic flattening on outer array structures

Similar as the example StackViews.jl example on repeated array. Suppose we have a 2-dimensional nested array A:

julia> using StackViews
julia> A = rand(100, 100);
julia> n = 100;
julia> StackView([A for _ in 1:n,_ in 1:n])
(100, 100, 10000)

We can see that StackView ignores the for loop structure, and flatten outer layer into a vector automatically. In principal, it should be an array with size (100,100,100,100). Is there anyway that we can persevere array size in StackView?

Start with the StackView constructor and the linked StackViews.jl repeated-array example. Trace how the outer array of arrays is interpreted and check existing tests or documentation for dimension handling. Done means nested outer dimensions are preserved for the shown construction, with coverage demonstrating the expected (100, 100, 100, 100) shape.
