    ECMA Section:       12.6.3 The for...in Statement
    Description:
    The production IterationStatement : for ( LeftHandSideExpression in Expression )
    Statement is evaluated as follows:
 .  Evaluate the Expression.
 .  Call GetValue(Result(1)).
 .  Call ToObject(Result(2)).
 .  Let C be "normal completion".
 .  Get the name of the next property of Result(3) that doesn't have the
    DontEnum attribute. If there is no such property, go to step 14.
 .  Evaluate the LeftHandSideExpression (it may be evaluated repeatedly).
 .  Call PutValue(Result(6), Result(5)).  PutValue( V, W ):
 .  If Type(V) is not Reference, generate a runtime error.
 .  Call GetBase(V).
 .  If Result(2) is null, go to step 6.
 .  Call the [[Put]] method of Result(2), passing GetPropertyName(V)
    for the property name and W for the value.
 .  Return.
 .  Call the [[Put]] method for the global object, passing
    GetPropertyName(V) for the property name and W for the value.
 .  Return.
 .  Evaluate Statement.
 .  If Result(8) is a value completion, change C to be "normal completion
    after value V" where V is the value carried by Result(8).
 . If Result(8) is a break completion, go to step 14.
 . If Result(8) is a continue completion, go to step 5.
 . If Result(8) is a return completion, return Result(8).
 . Go to step 5.
 . Return C.
