+// Package iter provides a syntactically different way to iterate over
+// integers. That's it.
+//
+// This package was intended to be an educational joke when it was
+// released in 2014. People didn't get the joke part and started
+// depending on it. That's fine, I guess. (This is the Internet.) But
+// it's kinda weird. It's one line, and not even idiomatic Go style. I
+// encourage you not to depend on this or write code like this, but I
+// do encourage you to read the code and think about the
+// representation of Go slices and why it doesn't allocate.
+package iter
+
+// N returns a slice of n 0-sized elements, suitable for ranging over.
+//
+// For example:
+//
+//    for i := range iter.N(10) {
+//        fmt.Println(i)
+//    }
+//
+// ... will print 0 to 9, inclusive.
+//
+// It does not cause any allocations.
