   > This included what was probably the most interesting part, writing the tricky recursive code to implement the match statement.

   Back in school I found this book[0], "The Implementation of Functional Programming Languages". Flipping through it was very neat because it kinda demystified the nuts and bolts of implementing the "fancier" functional programming features for me.

   Chapter 5 is about implementing pattern matching.

   You read this kind of stuff and realize how easy things become when you just tackle a problem with the right mindset and abstractions. And this is a book from 1987! We've always had decent answers for a lot of the stuff.

   I think it's interesting to flip through if you're a language implementer, though helps to be comfortable with reading some stuff sideways and not understanding every detail.

         In a completely unrelated thread to the topic you wrote the word porn 5 times. Are you sure it&#x27;s the neighbours you need to worry about?

            None of what I write is unrelated; if I wrote, there must have been a connection. Perhaps you can&#x27;t read?

               Indeed there must be a connection, which is why I advised you to look inwards!

                  And you haven&#x27;t? You must be a saint, then.
