The idea is that context is something you pass along in each of your calls. If your function body is a simple call, then it does not affect the context; the callee gets the same context as you are getting. So one can say that "want" is really one of the contextual variables that gets reassigned every time a function is called when a particular type is expected. Thanks, AudreyThread Previous
