I think Iterators is part of the base distribution. Correct? Alas, here it tells me

```julia
julia> using Iterators

`Base.Iterators` is in Base.

thx, k. apparently, it needs Base. in ‘using’, or else

```julia
julia> using Iterators
ERROR: ArgumentError: Package Iterators not found in current path:
- Run `Pkg.add("Iterators")` to install the Iterators package.

```

and this one gives the error. is this the old package? or a different one? is this an unpleasant name conflict, or are users supposed to use both, or one in lieu of the other, or … ?
