Having dimensions without names

[nalimilan]

By default the constructor uses A, B, etc. for the names of dimensions. AFAICT there is no way to avoid having a name at all. Would it be possible to use nothing for this? Currently it's accepted, but it still prints nothing:

julia> NamedArray(rand(2, 3), [1:2, 1:3], [nothing, nothing])
2×3 Named Array{Float64,2}
nothing ╲ nothing │        1         2         3
──────────────────┼─────────────────────────────
1                 │ 0.974647  0.607695  0.814261
2                 │ 0.458673  0.327957  0.734594

Maybe this could even be the default, as it doesn't sound very useful to generate arbitrary names. FWIW, R doesn't print anything when dimension names are NULL.

Yes this would make sense. Of course for now you can name your dimensions all ""

Also, it should be possible to have only named indexes for a subset of all dimensions.
