local function lang_list()
-- This list was generated using the following manual process:
-- 1) run query https://quarry.wmcloud.org/query/83535 which collected all
-- the sub-templates on commons and save results into a spreadsheet
-- 2) download list of language codes supported by MediaWiki from
-- https://gerrit.wikimedia.org/g/mediawiki/core/%2B/HEAD/includes/languages/data/Names.php
-- In 2024-12 there were 556 supported languages
-- 3) remove sub-templates which are not names of supported languages.
-- Use case sensative vlookup ("VLOOKUP(TRUE, CHOOSE({1,2}, EXACT(
-- lookup_value, lookup_array), return_array), 2, 0)".
-- In 2024-12 there were 274 supported languages used as subtemplates
-- 4) add a rank column to the spreadsheet (from 1 to 274)
-- 5) create "lang/rank" string, using "=CONCAT("'",A2,"/",E2,"', ")"
-- or something similar
-- 6) sort the rows by the language code, per
-- https://en.wikipedia.org/wiki/Wikipedia:Language_order_poll
-- 7) copy the results below
