Windows of Window(Left|Right) are not isolated from each other

[Orace]

List returned by Window* methods should be isolated from each other.

With current implementation, modifying one window will modify the next windows accordingly:

var sequence = Enumerable.Repeat(0, 3);
foreach (var window in sequence.Window(2))
{
  window[1] = 1; // modify the last element

  // on second iteration window[0] is 1 and this fail
  Assert.That(window[0], Is.EqualTo(0));
}

This is by-design. You are allowed to do what you want with the returned windows. What's important is that those windows are independent of each other as well as the original sequence from which they were created such that modifying an element through one window doesn't affect others or the source.

those windows are independent of each other

@atifaziz That is exactly what I show here: windows are not independent from each others
Modifying an element through one window may affect others !

Please reopen this issue.

In F#, Each window is returned as a fresh array.

I re-read the code and you're absolutely right. Sorry for closing this but your explanation and test in #653 didn't read clear enough. Thanks for persevering.
