I guess this doesn't really answer your question, but if you want, you can actually call the methods without explicitly stating the package - just import with a . in front of the names (but this is not recommended; see below):

package main

import (

  . "fmt"

  . "io/ioutil"

)

func main () {

  content, err := ReadFile("testfile")

  if err != nil {

    Println("Errors")

  }

  Println("My file:\n", string(content))

}

Note @jimt's comment below - this practice is not advised outside of tests as it could cause name conflicts with future releases. Also, definitely agree with @DavidGrayson's point of being nicer to read/see where things come from.
