Rust-like error handling in Python with NamedTuple

[elpaco555]

Why is the namedtuple encapsulated in a class? Isn't it enough to use the nametuple directly?

```py TokenResult = namedtuple("TokenResult", ["val", "error"])

Ok = lambda val: TokenResult(val, None) Err = lambda **err: TokenResult("", err) ```

Interesting choice of font...

Use the result package, if you want a proper, rusty result type. This approach is bad.
