 9.2.5 Evaluation of Function Forms
 ----------------------------------
 
 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’ (Calling Functions).  If the function is
 written in Lisp, the arguments are used to bind the argument variables
 of the function (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.
