[New-bugs-announce] [issue36060] Document how collections.ChainMap() determines iteration order

[Raymond Hettinger]

New submission from Raymond Hettinger <raymond.hettinger at gmail.com>:

Am working on a PR for this now.

Prior to regular dicts becoming ordered, the was no expectation for ChainMap() to have any particular order.  Now that such an expectation might exist, I need to document what ChainMap() does and perhaps why it does it.
