Changing the documentation to match does not necessarily make the code correct.
 In this case it means that the documentation is now broken as well.

There are clear advantages and disadvantages of both approaches, and reasonable people may disagree on the choice. I will close this; formerly map did cache its current element, to puzzlement by its users. I changed the behavior a long time ago, to much less puzzlement.
