  val s = Stream.from(1)
  s.take(2).foreach(_ => ())
  println(s)   // prints  Stream(1, 1, ?) (should be Stream(1, 2, ?), as it is in Scala 2.11.5)

  val s = Stream.from(1)
  s.take(2).foreach(_ => ())
  s.tail.head  // prints 2, which is correct

Let me know if I need to do any corrections or if this is a duplicate(searched but found no similar issue reported).

It's older than 2.11.6. 2.11.5 shows the same behavior in my hands. Also, there is an off-by-one error:

val s = Stream.from(1)
s.take(4).force
s   // Prints Stream(1, 2, 3, ?) even though 4 has been evaluated

A Scala community member on #scala/freenode told me it works fine on Scala 2.10 and Scala 2.11.5, probably they made a mistake about 2.11.5 version. I checked on Simply Scala and I was getting the expected correct result. (http://www.simplyscala.com/)

My bigger example also confirms off-by-one error.
