```julia
julia> using .Threads

julia> Threads
Base.Threads

```

[Modules docs says](https://docs.julialang.org/en/v1/manual/modules/#Submodules-and-relative-paths)

> A relative module qualifier starts with a period (.), which corresponds to the current module, and each successive . leads to the parent of the current module. This should be followed by modules if necessary, and eventually the actual name to access, all separated by .s.

but `Threads` isn’t relative to the current module. Why is a dot used?

`Threads` is exported from `Base` which is `used` in `Main` which is the current module in the REPL.
