If the first element of a list being evaluated is a Lisp function object,
byte-code object or primitive function object, then that list is a
function call. For example, here is a call to the function +:
(+ 1 x) |
The first step in evaluating a function call is to evaluate the remaining
elements of the list from left to right. The results are the actual
argument values, one value for each list element. The next step is to call
the function with this list of arguments, effectively using the function
apply (voir la section Calling Functions). If the function is written in
Lisp, the arguments are used to bind the argument variables of the function
(voir la section Lambda Expressions); then the forms in the function body are
evaluated in order, and the value of the last body form becomes the value of
the function call.
