    in which it is called.  It allows the definition of recursive
    functions which still work after being renamed, see example below.

## A trivial (but inefficient!) example:
fib <- function(n) if(n<=2) {if(n>=0) 1 else 0} else Recall(n-1) + Recall(n-2)
fibonacci <- .Alias(fib) ## renaming wouldn't work without Recall
fibonacci(10) # 55
