This library reminds me a lot of the code I've seen from junior developers trying to make things "cool" by removing a few characters of typing in exchange for library abstractions that create headaches down the line. I think features like this take years to naturally evolve in a codebase, on an as needed basis. And once that code base has evolved to reach something resembling non idiomatic Python, it can be quite hard to integrate new devs into the team. Such transitions into custom dsls or nifty tools are inevitable for large code bases, but I try to minimize it as much as possible, even when it hurts productivity. Long term maintainability is more important to me.
