scala case class private apply method( repl bug ?)

Question

in Scala2.10.0 REPL

Welcome to Scala version 2.10.0 (Java HotSpot(TM) 64-Bit Server VM, Java 1.7.0_13).
Type in expressions to have them evaluated. 
Type :help for more information.

scala> case class A private(i:Int)
defined class A

scala> A(1)
res0: A = A(1)

But if compile

$ scala -version
Scala code runner version 2.10.0 -- Copyright 2002-2012, LAMP/EPFL
$ cat Main.scala 
package foo

case class A private (i:Int)

object Main extends App{
  println(A(1))
}

$ scalac Main.scala 
Main.scala:6: error: constructor A in class A cannot be accessed in object Main
  println(A(1))
          ^
one error found

A.apply(1) is compile error.

is this Scala2.10.0 REPL bug?

FYI Scala2.9.2 REPL is following

Welcome to Scala version 2.9.2 (Java HotSpot(TM) 64-Bit Server VM, Java 1.7.0_13).
Type in expressions to have them evaluated.
Type :help for more information.

scala> case class A private(i:Int)
defined class A

scala> A(1)
<console>:10: error: constructor A in class A cannot be accessed in object $iw
              A(1)
              ^

Answer 1

This definitely looks like a REPL bug.

Note that the constructor is correctly marked as private (in other words, new A(1) does not compile, as expected), it is only the factory (A.apply) that is wrongly public.
