The original comment asked for enumerations. Despite him not realizing, Go has those. It has a relatively unique syntax for defining enums, sure, but enumerations are not defined by specific syntax. They are a higher level concept that transcends any specific syntax implementation. The original comment also hinted at wanting other features that some other languages have, including Pascal, although not stating which features specifically. I expect he was referring to wanting some kind of constraint system, which is the most common feature I hear requested of Go. But that's beyond the scope of enumerations.
