#### 3.5.1.4 Too Many Arguments ¶

It is not permitted to supply too many arguments to a function. Too many arguments means more arguments than the number of required parameters plus the number of optional parameters; however, if the function uses &rest or &key, it is not possible for it to receive too many arguments.

If this situation occurs in a safe call,

an error of type program-error must be signaled; and in an unsafe call the situation has undefined consequences.
