From: Tom Lord <lord@xxxxxxx> Subject: handling multiple scheme instances Date: Tue, 23 Dec 2003 15:29:16 -0800 (PST) > Every function should take an extra parameter which represents the > particular Scheme instance under consideration. I might be running > two different Scheme worlds in one process. To what extent should those Scheme instances share? (a) addess space : whether a reference to an object from one world can be passed to another world. (b) binding name space (symbol -> global variable mapping) : whether a global binding in one world is visible to another world or not. (c) control flow and data stack : whether you can "fork" a world to two worlds sharing the activation records. Related to this, I think the API concerning global bindings should take a context information corresponding to (b)---e.g. my Scheme needs "module" argument to determine which global binding the name refers. --shiro
