```julia
Vector{<:Number}

```

(see, for example, [Vector{Int} \<: Vector{Real} is false??? · JuliaNotes.jl](https://m3g.github.io/JuliaNotes.jl/stable/typevariance/) or this [Why [(a = 1, b = 3), (a = 3, b = 4)] isa Vector{NamedTuple} -\> false?](https://discourse.julialang.org/t/why-a-1-b-3-a-3-b-4-isa-vector-namedtuple-false/102981)).
