It's terrible, IMO, because every package that has generic words is now a variable name I can't use. A simple example which i find unreasonable:

  package main

  import (  
   "fmt"  
   "path/filepath"  
  )

  func main() {  
   filepath := filepath.Dir("./")  
   //filepath.Dir('./") -> This is now a string. Can't use filepath package anymore
   fmt.Println(filepath)  
  }

Now I have to make up variable names because `filepath` will shadow the package. How it this sensible in any shape? Zip just does this better by having @ in front of builtins.
