I’m looking at this [section](https://docs.julialang.org/en/stable/devdocs/subarrays/#Type-parameters-and-fields-1) where A is a `Array{Float64, 3}` and `S1 = view(A, :, 5, 2:6)`. I’m then confused by the explanation follows:

> If in our example above A is a Array{Float64, 3}, our S1 case above would be a SubArray{Int64,2,Array{Int64,3},Tuple{Colon,Int64,UnitRange{Int64}},false}.

Why isn’t it SubArray{ **Float64** ,2,Array{ **Float64** ,3},Tuple{Colon,Int64,UnitRange{Int64}},false}?

Thanks!

Fair enough. Thanks. One more question - Why `Colon` is changed to `Base.OneTo{Int64}`?
