For all exercises, let’s make sure we’re collaborating, not just submitting as quick as possible. We are a community of professionals - let’s learn from each other!

While we need working software, we also want well-crafted software. So once we’ve got a working solution, let’s see how we can improve it for flexibility and maintainability, rather than jumping right to the next one.

• Driver: Lean on your team! Talk through your reasoning! Pass the keyboard in 5 minutes or less!
• Navigators: Ask questions! Suggest improvements empathetically!
• Narrator: Nudge folks as needed! Stick with the Easy difficulty setting!

Example Exercises, with extra credit ideas/prompts

# General comment: I assume here that I'm just doing it wrong as I haven't been using Arel that long. 
#   If I knew for sure this was broken I'd just file a bug instead.

# Note that these specific ActiveRelations are just a trimmed-down example; the actual use case would 
#   really be better with a UNION, I promise.
