michael@0	8	File Name: 11.6.1-3.js
michael@0	9	ECMA Section: 11.6.1 The addition operator ( + )
michael@0	10	Description:
michael@0	11
michael@0	12	The addition operator either performs string concatenation or numeric
michael@0	13	addition.
michael@0	14
michael@0	15	The production AdditiveExpression : AdditiveExpression + MultiplicativeExpression
michael@0	16	is evaluated as follows:
michael@0	17
michael@0	18	1. Evaluate AdditiveExpression.
michael@0	19	2. Call GetValue(Result(1)).
michael@0	20	3. Evaluate MultiplicativeExpression.
michael@0	21	4. Call GetValue(Result(3)).
michael@0	22	5. Call ToPrimitive(Result(2)).
michael@0	23	6. Call ToPrimitive(Result(4)).
michael@0	24	7. If Type(Result(5)) is String or Type(Result(6)) is String, go to step 12.
michael@0	25	(Note that this step differs from step 3 in the algorithm for comparison
michael@0	26	for the relational operators in using or instead of and.)
michael@0	27	8. Call ToNumber(Result(5)).
michael@0	28	9. Call ToNumber(Result(6)).
michael@0	29	10. Apply the addition operation to Result(8) and Result(9). See the discussion below (11.6.3).
michael@0	30	11. Return Result(10).
michael@0	31	12. Call ToString(Result(5)).
michael@0	32	13. Call ToString(Result(6)).
michael@0	33	14. Concatenate Result(12) followed by Result(13).
michael@0	34	15. Return Result(14).
michael@0	35
michael@0	36	Note that no hint is provided in the calls to ToPrimitive in steps 5 and 6.
michael@0	37	All native ECMAScript objects except Date objects handle the absence of a
michael@0	38	hint as if the hint Number were given; Date objects handle the absence of a
michael@0	39	hint as if the hint String were given. Host objects may handle the absence
michael@0	40	of a hint in some other manner.
michael@0	41
michael@0	42	This test does only covers cases where the Additive or Mulplicative expression
michael@0	43	is a Date.
