Oh, yeah... I want to learn all of those! Sound interesting!
When it comes to languages, I want to collect all of them :-D Now, it is probably impossible for humans to master more than some 10-20 languages effectively and actively... but Miriam Makeba's language is an interesting candidate to know :-D
The other languages mentioned were Pawnee, Yupik, Silbo Gomero and Pirahâ.
