Eric Snow <ericsnowcurrently@gmail.com> added the comment: Thanks for working on this. Sorry I didn't get a chance to see your PR sooner. There was one small thing that needs to be changed back, as I implied in my comment on the PR [1]. Please undo the change in the text from "ordered mapping" to "dict". The original "is initialised as an empty ordered mapping" text line should be restored. "dict" is currently still not correct (the language spec does not dictate that dict be ordered). However, PEP 520 specifies that it must be ordered. Thanks!
