Personally this preciseness is just a distraction, but it sounds like you have learned from the constraints and can now take the training wheels off again.

Very curious about those cases, yet to find one myself that was not because of a bad design decision. Though I am also very big on the idea of `ambiguous grammar, rigorous implementation`, for natural language too. (Toki Pona is a somewhat extreme example but the contextual grammar, and holistic minimalism is fascinating)

Not to make it longer than needs to be; But take the example code in this readme: https://github.com/guzba/mummy

Being able to quickly script this without thinking about cases or style on the first pass is a really lovely way of reducing friction imho.
