In Object Oriented programming, yes, arrays are objects and the functions are a property of another object that can perform instructions on the data of the Array Object.
Similarly in Lisp, (a list-oriented language) both functions and arrays are lists.
This article however is discussing Haskel, a Functional Language, which means they are both functions.

In which Lisp? Try this in Common Lisp and it won't work too well:
What is the car of an array? An array in Lisp (since Lisp 1.5 at least, I haven't read earlier documentation) is an array, and not a list. It does not behave as a list in that you cannot construct it with cons, and you cannot deconstruct it with car or cdr.
