In class (scheme) we recently learned about the syntax that allows a function to take an arbitrary amount of arguments eg;
(define len
(lambda args
(length args)))
>(len 1 2 3)
3What are the advantages of using this form over simply passing the arguments as a single list in the first place? How do you even pass arguments to these kinds of functions within a program (and not on the command line)? Is there a way to make a procedure that returns a series of values that aren't wrapped within a list?
