Isn’t it a bit annoying that the display of an `Array{Union{Bool,Missing},N}` uses different conventions than than the display of an `Array{Bool,N}` ?

```julia
julia> x = [false,true]
2-element Vector{Bool}:
 0
 1

julia> y = [false,true,missing]
3-element Vector{Union{Missing, Bool}}:
 false
  true
      missing

```
