So I can’t do `module _ end`? Is that still consistent with “syntax requires a variable but the variable is never used”? It would be useful in creating different namespaces.

No. See [Anonymous or temporary module syntax · Issue #40189 · JuliaLang/julia · GitHub](https://github.com/JuliaLang/julia/issues/40189) — you can do

```julia
@eval Module() begin
    # put code here
end

```

to have an anonymous module.
