Still, does the naming sound right? Patterns that get "encoded" into the language, or made trivial by abstraction features within the language, are idioms?

No :/ The closest I've come, weirdly, was tutoring a friend through a design pattern class. Each time she'd come up and say, "The name of this week's pattern is such-and-such", and from that, I'd get 90% of the way to knowing that pattern was. I've always wanted just a simple list of the names, maybe with linked single paragraph descriptions, but every prior time I've looked I haven't been able to find one.

Yes! That's a favorite Ruby trick. Straight up tho - what is the formal name of doing that, specifically, the formal name of the category to which attr_accessor and has_many belong to?
