Yeah, I think it’s a lot like how you can have someone who is very experienced at using Bash as their shell, maybe even using pretty esoteric interactive features of Bash and line editing, but who has never touched Bash scripting.

Similarly, you can get a lot done in Rails with ‘just’ an understanding of how to read from, write to, and manipulate a handful of common classes (Hash, Array, String, etc.), and how to define and call methods, and little else. You barely need to know anything about Ruby classes/modules, beyond the difference between a class method and an instance method.
