1.12 + ECMA Section: 12.6.3 The for...in Statement
1.13 + Description:
1.14 + The production IterationStatement : for ( LeftHandSideExpression in Expression )
1.15 + Statement is evaluated as follows:
1.16 +
1.17 + 1. Evaluate the Expression.
1.18 + 2. Call GetValue(Result(1)).
1.19 + 3. Call ToObject(Result(2)).
1.20 + 4. Let C be "normal completion".
1.21 + 5. Get the name of the next property of Result(3) that doesn't have the
1.22 + DontEnum attribute. If there is no such property, go to step 14.
1.23 + 6. Evaluate the LeftHandSideExpression (it may be evaluated repeatedly).
1.24 + 7. Call PutValue(Result(6), Result(5)). PutValue( V, W ):
1.25 + 1. If Type(V) is not Reference, generate a runtime error.
1.26 + 2. Call GetBase(V).
1.27 + 3. If Result(2) is null, go to step 6.
1.28 + 4. Call the [[Put]] method of Result(2), passing GetPropertyName(V)
1.29 + for the property name and W for the value.
1.30 + 5. Return.
1.31 + 6. Call the [[Put]] method for the global object, passing
1.32 + GetPropertyName(V) for the property name and W for the value.
1.33 + 7. Return.
1.34 + 8. Evaluate Statement.
1.35 + 9. If Result(8) is a value completion, change C to be "normal completion
1.36 + after value V" where V is the value carried by Result(8).
1.37 + 10. If Result(8) is a break completion, go to step 14.
1.38 + 11. If Result(8) is a continue completion, go to step 5.
1.39 + 12. If Result(8) is a return completion, return Result(8).
1.40 + 13. Go to step 5.
1.41 + 14. Return C.
