This stumps me at the moment: How do I refer to `f` in the submodule?

```julia
module A

f(x) = 10*x

module SubA

g(x) = f(1)

end

end

using .A

@show A.SubA.g(3)

```

You need to pull `f` into `SubA` from `A` like so:

```julia
julia> module A
       f(x) = 10*x

       module SubA
       using ..A: f

       g(x) = f(1)

       end

       end
Main.A

julia> using .A

julia> A.SubA.g(3)
10

```

the `..A` basically means `$EnclosingModule.A` like in unixy directories.

Of course, I’ve used this notation many times before. I don’t know, when I looked at this particular example I couldn’t see it. Silly me.

Thanks.
