This is the first little library I try to put together in Python, and it was natural for me to hit it with all the relevant decorations as well as type annotations in order to expose *strict* contracts, plus hopefully have intellisense work all over the place. After several days of struggling, I am indeed finding that impossible in Python, at least with the available tools, and I am indeed going out of my way to just get some half-decent results... But, if I give up on strict contracts, I can as well give up on type annotations and the whole lot, indeed why even subclass ABC? Which is maybe too drastic, maybe not: it's the next thing I am going to try, and see what I remain with. :) Of course, any more hints welcome...
