Why do you want the runtime to check for the correct number of arguments rather than having your own function check? The language is very flexible and makes it easy to validate both missing and too many arguments if that's important to your usage.

One thing I wonder is why functions accept any number of arguments by default, instead of requiring an exact number (this is a pet peeve of mine, since I often call functions with the wrong number of arguments by accident). Functions which require a variable number of arguments (or optional arguments) could still use ... to get them.
