michael@0	8	File Name: 11.2.1-4-n.js
michael@0	9	ECMA Section: 11.2.1 Property Accessors
michael@0	10	Description:
michael@0	11
michael@0	12	Properties are accessed by name, using either the dot notation:
michael@0	13	MemberExpression . Identifier
michael@0	14	CallExpression . Identifier
michael@0	15
michael@0	16	or the bracket notation: MemberExpression [ Expression ]
michael@0	17	CallExpression [ Expression ]
michael@0	18
michael@0	19	The dot notation is explained by the following syntactic conversion:
michael@0	20	MemberExpression . Identifier
michael@0	21	is identical in its behavior to
michael@0	22	MemberExpression [ <identifier-string> ]
michael@0	23	and similarly
michael@0	24	CallExpression . Identifier
michael@0	25	is identical in its behavior to
michael@0	26	CallExpression [ <identifier-string> ]
michael@0	27	where <identifier-string> is a string literal containing the same sequence
michael@0	28	of characters as the Identifier.
michael@0	29
michael@0	30	The production MemberExpression : MemberExpression [ Expression ] is
michael@0	31	evaluated as follows:
michael@0	32
michael@0	33	1. Evaluate MemberExpression.
michael@0	34	2. Call GetValue(Result(1)).
michael@0	35	3. Evaluate Expression.
michael@0	36	4. Call GetValue(Result(3)).
michael@0	37	5. Call ToObject(Result(2)).
michael@0	38	6. Call ToString(Result(4)).
michael@0	39	7. Return a value of type Reference whose base object is Result(5) and
michael@0	40	whose property name is Result(6).
michael@0	41
michael@0	42	The production CallExpression : CallExpression [ Expression ] is evaluated
michael@0	43	in exactly the same manner, except that the contained CallExpression is
michael@0	44	evaluated in step 1.
