     File Name:          11.6.1-1.js
     ECMA Section:       11.6.1 The addition operator ( + )
     Description:
  
     The addition operator either performs string concatenation or numeric
     addition.
  
     The production AdditiveExpression : AdditiveExpression + MultiplicativeExpression
     is evaluated as follows:
  
     1.  Evaluate AdditiveExpression.
     2.  Call GetValue(Result(1)).
     3.  Evaluate MultiplicativeExpression.
     4.  Call GetValue(Result(3)).
     5.  Call ToPrimitive(Result(2)).
     6.  Call ToPrimitive(Result(4)).
     7.  If Type(Result(5)) is String or Type(Result(6)) is String, go to step 12.
     (Note that this step differs from step 3 in the algorithm for comparison
     for the relational operators in using or instead of and.)
     8.  Call ToNumber(Result(5)).
     9.  Call ToNumber(Result(6)).
     10. Apply the addition operation to Result(8) and Result(9). See the discussion below (11.6.3).
     11. Return Result(10).
     12. Call ToString(Result(5)).
     13. Call ToString(Result(6)).
     14. Concatenate Result(12) followed by Result(13).
     15. Return Result(14).
  
     Note that no hint is provided in the calls to ToPrimitive in steps 5 and 6.
     All native ECMAScript objects except Date objects handle the absence of a
     hint as if the hint Number were given; Date objects handle the absence of a
     hint as if the hint String were given. Host objects may handle the absence
     of a hint in some other manner.
  
     This test does not cover cases where the Additive or Mulplicative expression
     ToPrimitive is string.
