hcat and vcat drop names when first argument is a number

[mzgubic]

When the first argument is a NamedDimsArray then all is well, but if the first argument is a number then names are dropped:

julia> ndv = NamedDimsArray(rand(2), (:x,));

julia> vcat(1, ndv)
3-element Array{Float64,1}:
 1.0
 0.03803080414772442
 0.24045992283044382

julia> hcat(1, ndv')
1×3 Array{Float64,2}:
 1.0  0.0380308  0.24046

Should work as:

julia> hcat(ndv', 1)
1×3 NamedDimsArray{(:_, :x),Float64,2,Array{Float64,2}}:
 0.0380308  0.24046  1.0

Thanks @mcabbott for bringing this up

If you wanted to you could make all the hvcat methods work. For example, this should ideally be an error, but instead it has (almost) random names from a bug in similar:

julia> ndv = NamedDimsArray(rand(2), (:x,)); nda = NamedDimsArray(ones(2,2), (:y, :z));

julia> Float32[nda ndv
               ndv' 1]
3×3 NamedDimsArray{(:y, :z), Float32, 2, Matrix{Float32}}:
 1.0       1.0      0.398549
 1.0       1.0      0.88751
 0.398549  0.88751  1.0
