1. Less explicit to_s.

Like in joining arrays: records.map { |r| r.to_s }.join "\n"

Agg, get away casting! Could just be: records * "\n"

2. Forgetting grep works with classes.

I’ll be searching for a class: animals.find_all { |a| a.is_a? Hawk }

Rather: animals.grep Hawk

3. Structs for simple classes.

Object still needs an attrs method. Struct has members.

Object uses instance_variable_set. Struct uses []=.
