Nice as always @DeaMariaLeon  Thanks @mroeschke for reviewing and merging. I have some questions:

1. Do you prefer that I include more examples per PR or is "little by little" OK?
2. Should I avoid many commits and send just one? I think I should use `git rebase`..  > Do you prefer that I include more examples per PR or is "little by little" OK?

I am okay with more examples per PR. Personally, I would say no more than addressing 10 functions per PR

> Should I avoid many commits and send just one? I think I should use git rebase..

No need to worry about this. When your PRs are merged, the commits are squashed all together. OK, good to know both points. 
Thanks.
