> Which makes sense, it's got the smallest language spec of any of them
I think go is fairly small, too, but “size of spec” is not always a good measure for that. Some specs are very tight, others fairly loose, and tightness makes specs larger (example: Swift’s language reference doesn’t even claim to define the full language. https://docs.swift.org/swift-book/documentation/the-swift-pr...: “The grammar described here is intended to help you understand the language in more detail, rather than to allow you to directly implement a parser or compiler.”)

(Also, browsing golang’s spec, I think I spotted an error in https://go.dev/ref/spec#Integer_literals. The grammar says:
Given that, how can 0600 and 0_600 be valid integer literals in the examples?)
