“Oh no!”

“But we’re going out with a bang,” you say. “This chapter contains not one, not two, but ten additional patterns.”

They’re all good patterns, but some aren’t used often these days. And some are just plain hard to implement, like the Interpreter pattern, which says, “Given a language, define a representation for its grammar along with an interpreter that uses the representation to interpret sentences in the language.” That sounds like a good afternoon’s work.
