   Of course, we may also take advantage of an `import` statement:
  
positive.code: ----
  module Somewhere.Else
  
  import Foo.Bar
  
  function plop = {
    let result = f()
    let result_bis = Bar.f()
    let result_full = Foo.Bar.f()
    return result
  }

negative.code: ----
  module Somewhere.Else
  
  import foo.Bar
  
  function plop = {
    return f()
