Не е чак awful. (:

Като цяло нямаш добро разделение на отговорностите. Имаш два класа, единият се грижи за parse-ването, част от ArnoldC+- ключовите думи и част от контекста и друг - за останалата част. Личи си и че това разделение е изкуствено от постоянните if @runner.respond_to?.

Не става ясно кои са методи са дирекна имплементация на синтаксиса на езика и кои са някакви помощни методи.

Защо не използваш get_var в talk_to_the_hand?


Надявам се задачата да ти е била интересна и полезна. Както винаги, може да погледнеш нашето решение ако ти е интересно как ние сме решили да направим въпросното разделение.
