Overengineered Calculator project explores Zig language and QBE compiler

A recent blog post showcases an overengineered calculator implementation. The author chose the Zig language for its low‑level control and safety features. QBE, a small compiler backend, was integrated to handle code generation. The combination results in a highly modular yet intricate calculator design. The write‑up walks through the architecture and key implementation steps. It highlights challenges faced when marrying Zig with QBE’s compilation model. The project serves as a case study for language and compiler experimentation. Readers can follow the full source and discussion on the author’s website.
