15.2.14 array-has-fill-pointer-p | Function
  Syntax: array-has-fill-pointer-p array generalized-boolean Arguments and Values: array - an array. generalized-boolean - a generalized boolean. Description: Returns true if array has a fill pointer; otherwise returns false. Examples:
       (array-has-fill-pointer-p (make-array 4))  implementation-dependent
       (array-has-fill-pointer-p (make-array '(2 3)))  false
       (array-has-fill-pointer-p
         (make-array 8
                     :fill-pointer 2
                     :initial-element 'filler))  true
Exceptional Situations: Should signal an error of type type-error if its argument is not an array. See Also: make-array, fill-pointer Notes: Since arrays of rank other than one cannot have a fill pointer, array-has-fill-pointer-p always returns nil when its argument is such an array. Allegro CL Implementation Details: None.
