是的，请考虑以下示例：
package mainimport "fmt"// convert types take an int and return a string value.type convert func(int) string// value implements convert, returning x as string.func value(x int) string { return fmt.Sprintf("%v", x)}// quote123 passes 123 to convert func and returns quoted string.func quote123(fn convert) string { return fmt.Sprintf("%q", fn(123))}func main() { var result string result = value(123) fmt.Println(result) // Output: 123 result = quote123(value) fmt.Println(result) // Output: "123" result = quote123(func(x int) string { return fmt.Sprintf("%b", x) }) fmt.Println(result) // Output: "1111011" foo := func(x int) string { return "foo" } result = quote123(foo) fmt.Println(result) // Output: "foo" _ = convert(foo) // confirm foo satisfies convert at runtime // fails due to argument type // _ = convert(func(x float64) string { return "" })}播放：http：//play.golang.org/p/XNMtrDUDS0
