I think this is slightly misleading - this idiom doesn't skip three - it adds 3 to the current value of iota. For example, given const ( A = iota B C D = iota + 10 E F = iota + 2 G ) G will be 8, not 18. -- You received this message because you are subscribed to the Google Groups "golang-nuts" group.
