Is there a package which provides this?

I don’t want to use push!, I would like to concat and so on
Thanks

Just GitHub - JuliaArrays/StaticArrays.jl: Statically sized arrays for Julia?

Perhaps GitHub - JuliaCollections/FunctionalCollections.jl: Functional and persistent data structures for Julia is what you’re looking for?

You can use functional operations on mutable structures, too. If you don’t want to use push!, just don’t.
