Is this a known and desirable result?
I just tested this in in v"1.1.0" and the result is a Bool.
From the Doc (v1.2): “Note that comparisons such as `==` operate on whole arrays, giving a single boolean answer. Use dot operators like `.==` for elementwise comparisons. (For comparison operations like `<` , _only_ the elementwise `.<` version is applicable to arrays.)”
Julia v"1.2.0"
```
log.([1]) .< 0
> 1-element BitArray{1}:
> 0
log.([1; 1]) .< 0
> 2-element BitArray{1}:
> 0
> 0
log.([1, 1]) .< 0
> 2-element BitArray{1}:
> 0
> 0
[1, 1] .< [2, 2]
> 2-element BitArray{1}
> 1
> 1
```
whereas
```
log.((1, 1)) .< 0
> (false, false)
log.(1) .< 0
> false
```

The elements _are_ boolean. In Julia, `Bool` is a subtype of `Number` with `true == 1` and `false == 0`. When you print a whole array of boolean values (e.g. a `BitArray`), the elements simply print as `0` and `1` in Julia 1.2, rather than as `true` and `false`, for legibility and compactness.
```julia
julia> b = BitArray([true, false, true, true, false])
5-element BitArray{1}:
1
0
1
1
0
julia> b[2]
false
```

Nice!
I couldn’t find anything in the release notes or in the documentary, thanks for that!
