Why can't you do `tuple(dict.items())` to get your indexable pairs? Otherwise there are no plans as you would have to introduce a new method as you can't assume e.g. `0` is being used as a dictionary key. On Fri, Jun 26, 2020 at 10:32 AM Hans Ginzel <hans@matfyz.cz> wrote:

Hello,
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.
Use case: Represent database table metadata (columns). It is useful as to access columns both by name and by index as to insert column on specific position, https://dev.mysql.com/doc/refman/8.0/en/alter-table.html, “ALTER TABLE ADD COLUMN [FIRST |AFTER col]” (consider default order or table storage size optimisation by aligning).
Thank you in advance, Hans PS1: Named tuples cannot be used, are immutable.
