  17 ECMAScript Standard Built-in Objects:
    Every built-in Function object, including constructors, that is not
    identified as an anonymous function has a name property whose value
    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 }.
