I'm especially struck at the moment by what seems to me to be a bit of a contradiction. In this talk (https://www.youtube.com/watch?v=QboI_1WJUlM) from COFES, there's a clear push for a kind of simplicity and elegance that seems very opposite to the common criticisms I've seen of OOP, that it too easily results in overly-complex software (one Reddit comment I stumbled across from someone that seemed to have experience working on commercial Smalltalk applications said Smalltalk encourages an explosion of complexity). I'm keen to look at some good counter-examples.
So, Smalltalkers on HN, what's your favorite Smalltalk-family code and why?
