apply

(apply function &rest args)

Calls function with the leading arguments prepended to the elements of the final argument, which must be a list, and returns its result. As with funcall, function may be a function value (#'f, a lambda) or a quoted symbol designator. (apply #'+ 1 2 '(3 4)) is equivalent to (funcall #'+ 1 2 3 4); passing only the spread list as in (apply #'+ '(1 2 3)) works too.
