Kettled twice. Extra chewy, extra trustworthy.
Summary
The article presents a minimal 7-line interpreter for a functional programming language, demonstrating the eval/apply design pattern from Structure and Interpretation of Computer Programs (SICP). It argues that implementing a programming language is a valuable educational experience for programmers, fostering a deeper understanding of computation. The interpreter is Turing-equivalent and can be implemented in about 3 minutes, showcasing a scalable architecture found in many real-world interpreters.
