I had a very similar revelation to the OP in the article. Coincidentally, I also happened to be writing semantic analysis for a compiler using the visitor pattern. From this I can conclude two things: - It's definitely the wrong choice to do abstract syntax tree traversal using the visitor pattern. But what would be a better choice? When using Java? - Writing a compiler can be a life changing experience. These days I call myself a recovering object oriented programmer.
