+
+  18 ECMAScript Standard Built-in Objects:
+    Unless specified otherwise, a built-in object that is callable as a function
+    is a built-in function object with the characteristics described in 10.3.
+    Unless specified otherwise, the [[Extensible]] internal slot of a built-in
+    object initially has the value true.
+
+    Unless otherwise specified every built-in function and every built-in
+    constructor has the Function prototype object, which is the initial value
+    of the expression Function.prototype (20.2.3), as the value of its
+    [[Prototype]] internal slot.
+
+    Built-in function objects that are not identified as constructors do not
+    implement the [[Construct]] internal method unless otherwise specified in
+    the description of a particular function.
+includes: [isConstructor.js]
