Sure, in my workflow I make use of mypy and ruff extensively (but ruff does not allow plugins). So I decided to create several plugins with the intention of improving the developer experience and understanding of the code.

Now, what I am asking is, could we expand this by having static annotations that enforce runtime behaviours before running the code? I'm not advocating for the removal of the tests or some manual testing phase, but in the same vein of type errors being shown in our IDE, could we have static checks like contracts for functions or class invariants?

Full disclaimer: I leveraged AI technologies to create them.
