From the December 7, 1988, dpANS:

Page 24, lines 23-24:

   "An array type describes a contiguously allocated nonempty set of
   objects with a particular member object type, called the element
   type."

The key word is "object".  A function is not an object.

Page 23, lines 27-30:

   "Types are partitioned into object types (types that describe
   objects), function types (types that describe functions), and
   incomplete types (types that describe objects but lack information
   needed to determine their sizes)."
