For example:

```julia
julia> module A
           module B
               export f
               f(x) = 1
           end
       end
Main.A

julia> using .A: B

julia> f(1)
ERROR: UndefVarError: f not defined
Stacktrace:
 [1] top-level scope
   @ REPL[4]:1

```

Don’t you think that `using .A: B` should bring into scope the methods exported by `B`?

I think you want:

```julia
using .A.B

```

What you have now is only pulling in the name `B`.
