+  17 ECMAScript Standard Built-in Objects:
+
+    Every built-in function object, including constructors, has a length
+    property whose value is an integer. Unless otherwise specified, this
+    value is equal to the largest number of named arguments shown in the
+    subclause headings for the function description. Optional parameters
+    (which are indicated with brackets: [ ]) or rest parameters (which
+    are shown using the form «...name») are not included in the default
+    argument count.
+    Unless otherwise specified, the length property of a built-in function
+    object has the attributes { [[Writable]]: false, [[Enumerable]]: false,
+    [[Configurable]]: true }.
