A 300-Line Python Compiler: Closure Conversion Explained
2025-08-11
While working through the Ghuloum tutorial, the author re-implemented a compiler originally written in C, achieving a concise 300-line Python version (including tests). This compiler performs closure conversion, handling variable binding, free variable tracking, and code object management. The post details the implementation, covering `lambda` and `let` expressions, function calls, and providing test cases and assembly code examples. The result is a surprisingly compact compiler capable of handling closures and indirect function calls, showcasing elegant solutions to complex problems.
