How to "import static" like in Java? (No need to put package qualifier to access keywords)

Use dot as the alias of the import.

For example:

import . "fmt"

Now you can access Printf without typing fmt.Printf.

How to read from standard input and write to standard output?

os.Stdin and os.Stdout acts as automatically opened os.File, so you can read and write
to it. They are automatically io.Writer and io.Reader too, because they implement

func (file *File) Write(b []byte) (n int, err Error)
  and
func (file *File) Read(b []byte) (n int, err Error)

There is os.Stderr too.
