Wren is a small, fast, class-based concurrent scripting language
Haven't classes -- as things which house methods and fields together -- gone out of fashion? I think the same thing has happened with inheritance.<p>The ontological problem of "does the knife cut the cucumber" or "does the cucumber get cut with the knife" seems serious. The "is-a" relationship is also problematic, because does a square inherit both from rhombus and parallelogram?
