Unspeakably Evil Hacks in Service of Marginally Improved Syntax: "Compile-Time" Python Programming

Language Internals, Intermediate


One of Python's strengths as a dynamic language is its suite of powerful metaprogramming tools. What happens, however, when you want to move beyond the tools provided by "traditional" metaprogramming techniques? This talk will take the audience on a brief tour of projects and techniques that stretch the boundaries of what's possible in Python.


In this talk, we provide an introduction to several lesser-known techniques for hacking extending the functionality of Python. Along the way, we consider the costs (in clarity, portability, or otherwise) of employing nonstandard tools to work around limitations of Python.

Topics may include:
- Runtime Bytecode Rewriting (
- Hooking the Lexer with Custom Encodings (
- Import Hooks (,
