写入不存在的文件没有错误？

Why would f.Write() not return any error if I remove the file before I write?

package main

import (
    "fmt"
    "os"
    "time"
)

func main() {
    f, err := os.Create("foo")
    if err != nil {
        panic(err)
    }

    if err := os.Remove("foo"); err != nil {
        panic(err)
    }

    if _, err := f.Write([]byte("hello")); err != nil {
        panic(err) // would expect panic here
    }

    fmt.Println("no panic?")
}

Apparently this is expected.

When you delete a file you really remove a link to the file (to the inode). If someone already has that file open, they get to keep the file descriptor they have. The file remains on disk, taking up space, and can be written to and read from if you have access to it.
