Not generally afaik. This is fairly intentional in Racket's design. Though I wonder what your use cases are? Here are some routes you might explore, depending on what it is: - Use a "tagged hashmap" as a kind of cheap object structure - Use Racket's classes system, which *does* support runtime composition composition of classes (but not of extending an object already instantiated with a class) -- You received this message because you are subscribed to the Google Groups "Racket Users" group.
