+   Description:
+
+   For each formal parameter, as defined in the FormalParameterList, create
+   a property of the variable object whose name is the Identifier and whose
+   attributes are determined by the type of code. The values of the
+   parameters are supplied by the caller. If the caller supplies fewer
+   parameter values than there are formal parameters, the extra formal
+   parameters have value undefined. If two or more formal parameters share
+   the same name, hence the same property, the corresponding property is
+   given the value that was supplied for the last parameter with this name.
+   If the value of this last parameter was not supplied by the caller,
+   the value of the corresponding property is undefined.

+   File Name:          10.1.4-1.js
+   ECMA Section:       10.1.4 Scope Chain and Identifier Resolution
+   Description:
+   Every execution context has associated with it a scope chain. This is
+   logically a list of objects that are searched when binding an Identifier.
+   When control enters an execution context, the scope chain is created and
+   is populated with an initial set of objects, depending on the type of
+   code. When control leaves the execution context, the scope chain is
+   destroyed.
+
+   During execution, the scope chain of the execution context is affected
+   only by WithStatement. When execution enters a with block, the object
+   specified in the with statement is added to the front of the scope chain.
+   When execution leaves a with block, whether normally or via a break or
+   continue statement, the object is removed from the scope chain. The object
+   being removed will always be the first object in the scope chain.
+
+   During execution, the syntactic production PrimaryExpression : Identifier
+   is evaluated using the following algorithm:
+
+   1.  Get the next object in the scope chain. If there isn't one, go to step 5.
+   2.  Call the [[HasProperty]] method of Result(l), passing the Identifier as
+   the property.
+   3.  If Result(2) is true, return a value of type Reference whose base object
+   is Result(l) and whose property name is the Identifier.
+   4.  Go to step 1.
+   5.  Return a value of type Reference whose base object is null and whose
+   property name is the Identifier.
+   The result of binding an identifier is always a value of type Reference with
+   its member name component equal to the identifier string.

+   ECMA Section:       10.1.4 Scope Chain and Identifier Resolution
+   Description:
+   Every execution context has associated with it a scope chain. This is
+   logically a list of objects that are searched when binding an Identifier.
+   When control enters an execution context, the scope chain is created and
+   is populated with an initial set of objects, depending on the type of
+   code. When control leaves the execution context, the scope chain is
+   destroyed.
+
+   During execution, the scope chain of the execution context is affected
+   only by WithStatement. When execution enters a with block, the object
+   specified in the with statement is added to the front of the scope chain.
+   When execution leaves a with block, whether normally or via a break or
+   continue statement, the object is removed from the scope chain. The object
+   being removed will always be the first object in the scope chain.
+
+   During execution, the syntactic production PrimaryExpression : Identifier
+   is evaluated using the following algorithm:
+
+   1.  Get the next object in the scope chain. If there isn't one, go to step 5.
+   2.  Call the [[HasProperty]] method of Result(l), passing the Identifier as
+   the property.
+   3.  If Result(2) is true, return a value of type Reference whose base object
+   is Result(l) and whose property name is the Identifier.
+   4.  Go to step 1.
+   5.  Return a value of type Reference whose base object is null and whose
+   property name is the Identifier.
+   The result of binding an identifier is always a value of type Reference with
+   its member name component equal to the identifier string.

+

+
+   As control enters execution contexts, and as ECMAScript code is executed,

+   File Name:          10.1.8-2
+   ECMA Section:       Arguments Object
+   Description:
+
+   When control enters an execution context for declared function code,
+   anonymous code, or implementation-supplied code, an arguments object is
+   created and initialized as follows:
+
+   The [[Prototype]] of the arguments object is to the original Object
+   prototype object, the one that is the initial value of Object.prototype
+   (section 15.2.3.1).
+
+   A property is created with name callee and property attributes {DontEnum}.
+   The initial value of this property is the function object being executed.
+   This allows anonymous functions to be recursive.
+
+   A property is created with name length and property attributes {DontEnum}.
+   The initial value of this property is the number of actual parameter values
+   supplied by the caller.
+
+   For each non-negative integer, iarg, less than the value of the length
+   property, a property is created with name ToString(iarg) and property
+   attributes { DontEnum }. The initial value of this property is the value
+   of the corresponding actual parameter supplied by the caller. The first
+   actual parameter value corresponds to iarg = 0, the second to iarg = 1 and
+   so on. In the case when iarg is less than the number of formal parameters
+   for the function object, this property shares its value with the
+   corresponding property of the activation object. This means that changing
+   this property changes the corresponding property of the activation object
+   and vice versa. The value sharing mechanism depends on the implementation.

+   File Name:          10.2.3-2.js
+   ECMA Section:       10.2.3 Function and Anonymous Code
+   Description:
+
+   The scope chain is initialized to contain the activation object followed
+   by the global object. Variable instantiation is performed using the
+   activation by the global object. Variable instantiation is performed using
+   the activation object as the variable object and using property attributes
+   { DontDelete }. The caller provides the this value. If the this value
+   provided by the caller is not an object (including the case where it is
+   null), then the this value is the global object.
