# Here's a contrived example of a LEFT JOIN using ARel. This is an example of
# the mechanics, not a real-world use case.

# NOTE: In the gist comments, @ozydingo linked their general-purpose ActiveRecord
# extension that works for any named association. That's what I really wanted!
# Go use that! Go: https://gist.github.com/ozydingo/70de96ad57ab69003446
