The Io language is a very simple & elegant homoiconic language. It was introduced as one of the seven languages in the '7 Languages in 7 Weeks' book. It's basically influenced by Lisp and Self, Smalltalk. Two of the best Io-related blog posts by _why: * Io Has a Very Clean Mirror - https://viewsourcecode.org/why/hackety.org/2008/01/05/ioHasA... * Lazy Bricks, Lazy Mortar - https://viewsourcecode.org/why/hackety.org/2008/01/10/lazyBr...

This is one of the languages covered in the excellent Prag Prog book "7 Languages in 7 Weeks" (https://pragprog.com/book/btlang/seven-languages-in-seven-we...).

One thing I would have liked to find was a use case. What problem can I solve more easily or elegantly in Io than in the languages I currently use? I've checked out both Juila and Go because they showed me how to do something I wanted to do in a way that was really nice. Without that, I don't have much to motivate me to play with it.
