* However, by this point another thread may have caused `lcname` to be added in the interned string table.
* This will cause `lcname` to get freed once it is found in the interned string table. If we were to use
* LITERAL_STR() here we would not change the `lcname` pointer to the new value, and it would point to the
* now-freed string. This will cause issues when we use `lcname` in the code below. We solve this by using
