Haha lovely, clearly we are in agreement here. You even put that in your book isn't it? > The Visitor pattern is really about approximating the functional style within an OOP language (source: https://craftinginterpreters.com/representing-code.html) The expression problem is one of those "mathematical duality" or yin-yang thing in software design that are less well-known for some reason. People keep pointlessly arguing in favor of one or another without knowing this duality. Another favorite of mine is SQL vs NoSQL which Erik Meijer mathematically proved to be dual of each other using category theory (https://queue.acm.org/detail.cfm?id=1961297). |
