+1 from me too.

+1, as Guido correctly recalls, this language guarantee will work well with Jython when we get to the point of implementing 3.7+.

So let's just document this as a language guarantee. On Sat, Nov 4, 2017 at 10:30 AM, Stefan Krah <stefan at bytereef.org_ _<mailto:stefan at bytereef.org>> wrote:
Hello, would it be possible to guarantee that dict literals are ordered in v3.7? The issue is well-known and the workarounds are tedious, example: https://mail.python.org/pipermail/python-ideas/2015-December/037423.html <https://mail.python.org/pipermail/python-ideas/2015-December/037423.html> If the feature is guaranteed now, people can rely on it around v3.9.
