I am sorry but I don’t understand the question. Generally for `Vector{T}` you don’t get to choose a storage model for a given `T`.

`Vector{T}` is not necessarily optimal for `pushfirst!` — again, if you want a deque, use a deque. AFAIK neither is “scattered in different chunks”.

FWIW, I don’t find it helpful to think about the data structure “behind” `Vector` when programming Julia. `Array`s are _the_ data structure _per se_.
