I created a #python package earlier this year for FastAPI-like development of AWS Lambda functions (routing, model validation). We’ve had it in production for ~4 months, but I didn’t want to release it until it was fully type-checked.

This turn out to be a nightmare! I hit several mypy bugs and edge cases, but learned tons and declared victory earlier today. I plan to release it in the next few weeks, once I’ve caught up on all the work I neglected in the process… 😫
