feat: cache IANA TLDs for faster lookups by salty-horse · Pull Request #390 · python-validators/validators
I wasn't sure what was meant by using dataclass, as this isn't a data-first class. I used a regular class, instead.
One thing that's obviously missing is tests. I'm not familiar with pytest, and don't know how to re-run the existing domain tests after running the new "load" function.
