New submission from Eric Snow <ericsnowcurrently at gmail.com>:
As of 3.7 [1], dict is guaranteed to preserve insertion order:
the insertion-order preservation nature of dict
objects has been declared to be an official part
of the Python language spec.
However, at least one key part of the language reference [2] was not updated to reflect this: "3.2. The standard type hierarchy" > "Mappings" > "Dictionaries".
Note that the library docs [3] *were* updated.
