Yes unfortunately my example is not very readable, but it was to illustrate the idea of including the sources of the called functions. Indeed, many IDEs allow you to easily display the source code of one function at a time, by navigating to the sources of the function or by displaying it in a pop-up, but the idea I had in mind is to be able to view the source code of the function with all its dependencies at a glance.
