:import command inside Scala REPL

Question

It's said in the book Scala in Action that using :import command inside Scala REPL we will see:

scala> :imports 
    1) import java.lang._       (153 types, 158 terms)
    2) import scala._           (798 types, 806 terms)
    3) import scala.Predef._    (16 types, 167 terms, 96 are implicit)

And according to this book those packages above are all automatically imported. But in my REPL (Scala 2.10.2) it returns only one line:

scala> :imports
     1) import scala.Predef._   (162 terms, 78 are implicit)

Is there something wrong?
