Hello,

On the following example, how would you test if a module has another module as a parent or grand parent?

```julia
module MyModule
    module MySubModule
             module MySubSubModule end
    end
end

```

NOTE: I would prefer a solution that doesn’t compare the names of the modules because I’m worried that it would not be robust

thanks! I’ll make a utility function that uses `parentmodule` and that will do 👍
