This is how I see it: A ThreadLocal is an object instance. It ensures a different object for each different thread. It implements automatic thread-confinement. In particular, a ThreadLocal may be referenced by different vars. You may move its reference around the program and it will refer to the same object by the same thread. Scoping refers to the ability to refer to a var. Dynamic scoping lets you use a var that should be declared by one of the functions up in the call stack. It implements an implicitly injected parameter to a function. A function that uses a dynamic var will see a different var depending on the last function in the call stack that defined it. > -- You received this message because you are subscribed to the Google Groups "Clojure" group.
