@mauve I'm a big fan of https://github.com/deckarep/golang-set . It's not in the standard library, but 🤷
@mauve What I noticed in Python, which has sets not just in stdlib but right in built-ins, is that many people don't know them enough and almost never utilize. When I use sets, they often ask on review "sets can do that? O.o" I've even seen beginners' books that don't cover sets at all. I wish people would appreciate sets more.
@mauve That one is actually surprising.
