While I don't think the slice changes are particularly out of character for Go, its simplicity is in general somewhat superficial. The type system is unsound and lacks power (although the interfaces are mostly nice), there are no generics (except for builtin collections), error handling is hard to compose (except in non-idiomatic ways), no real type inference (although single assignments are easier). Its simplicity is not composable.
