If stack is not an explicit transform it’s hard to understand what causes the stack. In this case it’s implicit based on the fill option which is not reflected in this shortened view. I suggest picking a more explicit example

That's a good point -- my thought was that the most common(?) stacking is done implicitly, so this example allows someone to explore the common stack parameters (offset, order). That said, I went back and forth on this quite a bit, and will explore some alternatives and keep this suggestion in the backlog.
