+ 17 ECMAScript Standard Built-in Objects:
+ Every built-in Function object, including constructors, that is not

+ is a String.
+
+ Unless otherwise specified, the name property of a built-in Function
+ object, if it exists, has the attributes { [[Writable]]: false,
+ [[Enumerable]]: false, [[Configurable]]: true }.
