Setting a module attribute from a function in a different module

[joey_the_snake]

I have 2 modules, one of them has a function that returns a list and the other one is using that function to create a module attribute.

Is this a safe operation in Elixir? I’m not sure if it’s guaranteed that the first module will be compiled before the second one. Also, does it matter if the modules are in the same file/different files?

e.g:

defmodule Producer do
  def special_list do
    [1,2,3]
  end
end

defmodule Consumer do
  @special_attribute Producer.special_list()
end
