if you run:

var rec = 0
def llRange(lo: Int, hi: Int): LazyList[Int] = {
  rec = rec + 1
  if (lo >= hi) LazyList.empty
  else LazyList.cons(lo, llRange(lo + 1, hi))
}
llRange(1, 10).take(3).toList

rec

you will get result 3 not 4

Correct lazy list expectation

I've replicated this result in a few Scala 2.13 versions. It's
not clear to me why in #216, the result seems
to be the opposite. This PR is now a bit
of a smoke test for that build failure.
