```julia
module A
  using B
end

```

is there `somefunction(A)` that returns a list which contains `:B` ? If `B` is imported, `names` does the job:

```julia
module A
  import B
end
names(A, imported=true) # [:A, :B]

```

I’d ideally like something that can cover both cases (import+using). (The use case is to be able to check that `A.B` will work, I can explicitly check this but it doesn’t feel like the right approach)

Hmm, after looking at the julia code for `getglobal` I stumbled upon `isdefined` which is what I should be using it seems:

```julia
isdefined(A, :B) # true

```
