Suppose a function pointer can be called with fewer actual arguments

such a call is made, the missing arguments will always be assigned the
default initialization for their types (default default-arguments!).
Now suppose that a language mechanism is provided so that code in the
function body can determine how many actual arguments were supplied at
the point of call.
Now any function pointer can simulate other default arguments
(non-default default arguments) by testing the actual number of
arguments supplied and assigning defaults overtly to the remainder
inside the function body. No need for new types: this is a run-time
action.
That's a great idea Carl!
You *do* know you're talking to yourself, right?
