`Slices` on Julia 1.9

On Julia 1.8 we have

julia> slices = eachslice(ones(2, 3, 4); dims=2)
Base.Generator{Base.OneTo{Int64}, Base.var"#245#246"{Array{Float64, 3}, Tuple{Colon}, Tuple{Colon}}}(Base.var"#245#246"{Array{Float64, 3}, Tuple{Colon}, Tuple{Colon}}([1.0 1.0 1.0; 1.0 1.0 1.0;;; 1.0 1.0 1.0; 1.0 1.0 1.0;;; 1.0 1.0 1.0; 1.0 1.0 1.0;;; 1.0 1.0 1.0; 1.0 1.0 1.0], (Colon(),), (Colon(),)), Base.OneTo(3))

julia> eltype(slices)
Any

julia> slices[1]
ERROR: MethodError: no method matching getindex(::Base.Generator{Base.OneTo{Int64}, Base.var"#245#246"{Array{Float64, 3}, Tuple{Colon}, Tuple{Colon}}}, ::Int64)

while on Julia 1.9, we have

julia> slices = eachslice(ones(2, 3, 4); dims=2)
3-element Slices{Array{Float64, 3}, Tuple{Colon, Int64, Colon}, Tuple{Base.OneTo{Int64}}, SubArray{Float64, 2, Array{Float64, 3}, Tuple{Base.Slice{Base.OneTo{Int64}}, Int64, Base.Slice{Base.OneTo{Int64}}}, false}, 1}:

 [1.0 1.0 1.0 1.0; 1.0 1.0 1.0 1.0]

julia> eltype(slices)
SubArray{Float64, 2, Array{Float64, 3}, Tuple{Base.Slice{Base.OneTo{Int64}}, Int64, Base.Slice{Base.OneTo{Int64}}}, false}
