Coconut VS effect

> to be part of the Python ecosystem

I'd rather use Python if I'm in the Python ecosystem. So many attempts were made in the past to make a new language compatible with the Python ecosystem (look up hylang and coconu -- https://github.com/evhub/coconut). But at the end of the day, I'd come back to Python because if there's one thing I've learnt in recent years it's this:

    minimize dependencies at all costs.

Have you had a look at Coconut? I don't know if it'll push all your buttons but whenever I hear someone who's reasonably content with Python but wants more FP goodies I always think of it. https://github.com/evhub/coconut . It's basically a superset of Python3 that transpiles into Python3 and is compatible with MyPy. I don't think I'd code Python w/o it ever again assuming I had the choice. The biggest negative for me is that there's no IDE support for the language last I looked, though of course you can work with the transpiler output (plain Python) in your favorite Python IDE. It might be fun to play around with, I know that I really enjoyed it but then I got spoiled by the language+tooling of Scala3, but if you don't have that option ...

If you're looking for suggestions I want to put forward zig lang if you like C/C++ and Coconut Lang if you like Python!

F# and also the fun, compile-to-Python, functional language called Coconut.

Effect is a functional library for building and composing asynchronous, concurrent, and reactive programs in TypeScript. It focuses on providing a robust and type-safe way to manage side effects in your programs.

Just use a library that already contains this and more functional programming idioms, like fp-ts or its successor, Effect [0]. It is a little more complex to learn but much more robust that simply implementing your own Result and other types.
