# "Which Go web framework should I use" and "how do I handle errors in Iris"
# are now answered inside an assistant at least as often as in a results page.
# Being absent from that answer costs more than any crawl budget it saves, and
# an assistant that cannot read this site will answer from a 2019 blog post
# about v11 instead.
