-The class method +Array.wrap+ behaves like the function +Array()+ except that it does not try to call +to_a+ on its argument. That changes the behavior for enumerables:
+The class method +Array.wrap+ behaves like the function +Array()+ except:
+
+* If the argument responds to +to_ary+ the method is invoked. <tt>Kernel#Array</tt> moves on to try +to_a+ if the returned value is +nil+, but <tt>Arraw.wrap</tt> returns such a +nil+ right away.
+* If the returned value from +to_ary+ is neither +nil+ nor an +Array+ object, <tt>Kernel#Array</tt> raises an exception, while <tt>Array.wrap</tt> does not, it just returns the value.
+* It does not call +to_a+ on the argument, though special-cases +nil+ to return an empty array.
