Example
The value of iota is still incremented for every entry in a constant list even if iota is not used:
const ( // iota is reset to 0
a = 1 << iota // a == 1
b = 1 << iota // b == 2
c = 3 // c == 3 (iota is not used but still incremented)
d = 1 << iota // d == 8
)
it will also be incremented even if no constant is created at all, meaning the empty identifier can be used to skip values entirely:
const (
a = iota // a = 0
_ // iota is incremented
b // b = 2
)
The first code block was taken from the Go Spec (CC-BY 3.0).
