While it does solve the problem with functools.partial() forcing you to use keyword arguments in some cases, I don't think currying is a common enough operation to warrant a whole lib, or even a new syntax.
I'd rather see partial() promoted to a universal static method attached to any callable, so it's easier to discover, and use.
I guess it depends what kind of stuff you're working on. I do a lot of work with jax for my research (https://github.com/google/jax) and use functools.partial a lot.
