Can someone please explain why the following errors?

```julia
macro d(np::Integer)
    quote
        using Distributed
        addprocs($np)
        @everywhere begin
            using Pkg
            Pkg.activate(".")
        end
    end
end

julia> @d 2
ERROR: LoadError: UndefVarError: @everywhere not defined

```

(I often add the body of the macro as boiler-plate code when I want to parallelize my code, so I was hoping to write a macro to reduce the number of lines of code I have to add.)

If I split it into two macros (one with `using Distributed; addprocs($np)`, and the other with the `@everywhere` block) it works. It also works if I use `using Distributed` before calling `@d`.

I also don’t know why the call to `addprocs` doesn’t error. If `@everywhere` isn’t defined, I would expect `addprocs` to be undefined as well.
