thank you for making dict ordered. Is it planned to access key,value pair(s) by index? See https://stackoverflow.com/a/44687752/2556118 for example. Both for reading and (re)writing? Is it planned to insert pair(s) on exact index? Or generally to slice? See splice() in Perl, https://perldoc.perl.org/functions/splice.html. …
These are odd requirements.
No - Python dictionaries are ordered, by order of insertion only, but one can't generally do any manipulation by the numeric index of a dictionary entry - and it will stay that way.
That is fully corret to respect the _insertion_ order.
If you need such an hybrid data structure, you could just have a list of tuples as data structure, and use collections.abc.MutableMapping to provide a dict-like interface to it (an index for better than linear search).
I could create such a data structure if you want,
Thank you, I will write it myself. H.
