I don't really understand why "a new codebase is easy to learn" has anything to
do with where stuff "was actually defined". Either you can navigate easily
through the codebase with your editor/tooling or you cannot. And if you cannot,
putting the module name in front of everything doesn't help either, you still
have to manually open the file and then search for the declaration within this
file, so it's a search either way and you might as well start with the search
operation. (grep on the directory instead of on the file, for example).
