Hi!
Just curious... About:
" don't use relative imports like the one you posted from the "The Way to
Go", that is't really what you are supposed to do. "
Why?
What is the difference with "you are supposed to do"? what is the behavior
of using the dot?
In other worlds, like NodeJS, it's very common to have local code consumed
in that way. And it is independent of any package directory structure.
