The bytecode interpreter in the second half of the book doesn't use the visitor pattern.
Why?
The visitor pattern is very common in programming language implementations. I've seen it in the Rust compiler, in the Java Compiler, in the Go compiler and in the Roslyn C# compiler. Also used extensively in JetBrains' IDEs.
What do you have against this pattern? Or what is a better alternative?
