description: Subclassed Function instances has length and name properties
info: |
19.2.4.2 name
The value of the name property is an String that is descriptive of the
function. The name has no semantic significance but is typically a variable or
property name that is used to refer to the function at its point of definition
in ECMAScript code. This property has the attributes { [[Writable]]: false,
[[Enumerable]]: false, [[Configurable]]: true }.
Anonymous functions objects that do not have a contextual name associated with
them by this specification do not have a name own property but inherit the
name property of %FunctionPrototype%.
