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. PS2: See https://metacpan.org/pod/perlref#Pseudo-hashes:-Using-an-array-as-a-hash
