When debugging, add the package-level statement var _ = fmt.Println to avoid unused errors. Here's an example: http://play.golang.org/p/cZtmILYWoZ

Even easier: just add _ before you import:

  import (
     _ "fmt"
  )

To prevent the unused var error you can assign the var to an _ as well:

  _ = unusedVar

> Even easier: just add _ before you import

How is that an improvement? That's just as much work as commenting the line out.

Except that in this case, you can still use the package.

You're right, didn't know about the shadowed part.
