You don't need to put these requires inside the module blocks.

Instead, you could write:

(module MyLib
  (module TestData
    (FOO = "abc")
  end)
end)

(module MyLib
  (class Tool
  end)
end)

(module MyLib
  (class Motor
    (def something
      (TestData::FOO)
    end)
  end)
end)

That is,  if you  avoid the (class  Abc::Def::Ghi ... end)  form, then
modules namespaces will be created automatically when needed.

Then, how you spread the forms over files and execute require is up to
you and doesn't matter much.
