alt Hacker Newsswiss tables were invented by engineers working at google's zurich office, hence the name
im surprised that go, a programming language also from google, wasn't using them!
for an excellent talk on the development of swiss tables i highly recommend this talk by Matt Kulukundis at CppCon 2017: "Designing a fast, efficient, cache-friendly hash table, step by step" https://youtu.be/ncHmEUmJZf4
Go is much older than Swiss Tables. Since the hash table is a widely used container type and Go aspires to having a sort of "kitchen sink" stdlib I assume Go 1.0 had a hash table, and it can't be a Swiss Table because those weren't invented yet.
