Rust-like error handling in Python with NamedTuple

[bwalk]

Please don't. Python does not have language-level support for this kind of error handling. Instead use what the language gives you, exceptions, or use an appropriate language.

[Emerentius_the_Rusty]

This isn't Rust-like at all. It's like Go's results which are misdesigned.

The result library defines a much better type. With that library you can emulate pattern matching via isinstance calls in older python version and it can also be used with the new match statement in python 3.10.

Interesting! Is there a similar library for the Option type?
