I’ve never understood returns (https://github.com/dry-python/returns), is it just a gimmick or do people actually use it? It seems like it would be awkward to use and is working against how the language was designed.
I’m increasingly convinced that Python/JS-style duck typing is always a mistake, since you can’t do default function impls for traits. Just use inheritance.
Rust’s enums are even weirder, since they mix structuring with discrimination. You end up having to write everything twice most of the time. Again, use inheritance, though you’ll have to choose between

chains and virtual function calls.Python’s
pathlib
has a major footgun in that./foo
collapses tofoo
, negating the main point of writing it that way in the first place.More obnoxiously than that even, imo, it’s that pathlib removes trailing slashes. Its impossible (afaict) to reproduce
path.join(‘a’, ‘b/‘)
with pathlib
