package main

import (
"fmt"
)

type Integer int

func (a Integer) Less(b Integer) bool {
return a < b
}

func main() {
var a Integer = 1
if a.Less(2) {
fmt.Println("Less true.")
}
}

结果输出：Less true.

package main

import (
"fmt"
)

func modifyslice(array []int) {
slice1 := array[1:2]
fmt.Println(slice1)
slice1[0] = 4
fmt.Println(slice1)
fmt.Println(array)
}

func main() {
modifyslice([]int{1,2,3})

}

结果输出：
[2]
[4]
[1 4 3]

var file1 Writer = ...
if file5, ok := file1.(two.IStream); ok {
...
}
