In Axol's blog, the author discusses the merits of Test-Driven Development (TDD) while addressing common misconceptions. They emphasize that TDD encourages developers to write tests for edge cases, as proper adherence to TDD can highlight potential oversights in the code. However, the author notes that identifying these edge cases can be challenging, particularly before most of the code is written. Additionally, the blog highlights how TDD can serve as effective "guardrails" when outsourcing implementation tasks. Unlike written

Tree Calculus is a programming framework that allows for program analysis directly through its built-in reduction rules, enabling type checking, compilation, and optimization without the need for external tools. It supports a variety of type systems and integrates static and dynamic checks seamlessly. This framework enables the compilation and deployment of programs from within the program itself, leading to powerful interactive environments akin to Jupyter Notebooks for managing entire product lifecycles. Tree Calculus is Turing-complete and focuses on a trivial abstract syntax where
