+  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 }.
