I agree that this is a silly idea, but I actually thought that it could be done
by clever manipulation of the call stack. It can if you do the assignment with
assign():
> foo <- function()sys.calls()[[1]][[2]]
> assign("z", foo())
> z
[1] "z"
> assign("bah", foo())
> bah
[1] "bah"
but if you do x <- foo(), there is no mention of x or "x" in sys.calls().
Anyways, functions that assume being called in a specific are asking for
trouble in all cases where they get called differently.
