[go-nuts] Why Doesn't "len()" Work With Structs?

[jlfo...@berkeley.edu]

I noticed that the len() function doesn't take a struct as an argument (see 
below).
This is a big surprise. Can someone shed some light on why this restriction 
exists?

Cordially,
Jon Forrest

----------
package main

import "fmt"

var s struct {
        i1      int
        i2      int
}

func main() {
       fmt.Printf("len(s) = %d\n", len(s)) // -- invalid argument s (type 
struct { i1 int; i2 int }) for len
}
