OK, gotcha. Somehow, I thought "strategy" was more general than just a single method/function to plug in. (confession: I have the GoF book, but don't remember every section) I think one of the best points PG (of YC) ever made was about programmers thinking in a particular language. "If Blub doesn't do it, you don't need it" (paraphrasing). Convincing the C++/Java/C# fans they need other features sometimes is quite hard.
