apply and funcall are alternative ways to call a function whose name is computed; their arguments are supplied in different ways, so that explicit construction of Lisp code is not required, as it is for eval.
(apply fn list-of-args) applies the function fn to the arguments in the list list-of-args. Both arguments of apply are first evaluated.
(setq myfun #'+) (apply myfun '(2 3)) = 5
(funcall fn arg1 ... argn ) calls the function fn with the arguments arg1 ... argn . All arguments of funcall are evaluated.
(funcall (get (get object 'shape) 'drawing-program) (get object 'position) (get object 'size))
