Iterate over objects (WP-CLI)

There seems to be no obvious way to iterate over a collection of objects, like posts or taxonomy terms. To add insult to injury: WP-CLI commands that return object-IDs, are often limited to max. 100 items at a time.

Currently, this seems a quite good approach. It's only two lines of code, and it is much faster than using a 100% WP-CLI approach:

i='select term_id from wp_terms join wp_term_taxonomy using (term_id) where taxonomy like "pa_as%"'
mapfile -t j < <( wp db query "$i" --skip-column-names )

echo ${j[@]}
echo "# of entries: ${#j[@]}"
echo ${!j[@]}
echo "Entry 5: ${j[5]}"

• I tend to rewrite the mapfile line to mapfile -t j < <( wp db query "$i" --skip-column-names | grep . ), but it doesn't seem necessary here.
• --skip-column-names is a mysql Client option → https://dev.mysql.com/doc/refman/8.0/en/mysql-command-options.html
• It's so simple, that I don't even see the point of turning this into a function to be incorporated in some general WP-CLI-Bash library.
