The fourth and final article in the series: https://smalltalk.tech.blog/2020/01/29/extending-the-smalltalk-syntax-4/. Leandro Caniglia did a great job! These kinds of articles showcase Smalltalk/Pharo in a wonderful way. Lorenzo Schiavina will be submitting an article in the very near future. I'm really looking forward to it! Anybody else care to participate?
