+ * True when Term is a term with functor Name/Arity. If Term is a variable it is unified with a new term whose
+ * arguments are all different variables (such a term is called a skeleton). If Term is atomic, Arity will be unified
+ * with the integer 0, and Name will be unified with Term. Raises instantiation_error() if Term is unbound and
+ * Name/Arity is insufficiently instantiated.
+ *
+ * SWI-Prolog also supports terms with arity 0, as in a() (see
+ * [section 5](https://www.swi-prolog.org/pldoc/man?section=extensions)). Such terms must be processed using functor/4
+ * or compound_name_arity/3. The predicate functor/3 and =../2 raise a domain_error when faced with these terms.
+ * Without this precaution a round trip of a term with arity 0 over functor/3 would create an atom.
