Which we may not know, especially if we're tail-calling into something that hasn't been compiled yet. But I think the default should be to assume that the callee doesn't use caller, and then maybe have some trait or pragma that overrides that default if we want to pessimize. In any event, many uses of caller probably want to skip the middleman anyway, and even more uses of "want". It's the debugger that wishes the tail-call optimization didn't exist... Larry
