/*
|
||
|
|
* If a property put base value is not an object, the PutValue() algorithm
|
||
|
|
* will reject any attempt to create or update a data property on the
|
||
|
|
* temporary object created by coercion.
|
||
|
|
*
|
||
|
|
* This only has a visible effect in strict mode.
|
||
|
|
*
|
||
|
|
* See E5 Section 8.7.2, step 7.a of the variant [[Put]] algorithm.
|
||
|
|
*
|
||
|
|
* Note that the check in E5 Section 8.7.2, step 4 seems impossible to
|
||
|
|
* trigger. The possible temporary objects created are: Boolean, Number,
|
||
|
|
* String. Boolean and Number have no "own properties" while String has
|
||
|
|
* only non-writable properties which would trigger the [[CanPut]] check
|
||
|
|
* in step 2 so step 4 would never be reached.
