以往,各地“即买即退”服务往往仅覆盖本地口岸离境业务。跨城市旅行,体验难免打折。对此,多地正探索破题:广东省内,天津与北京,重庆与四川、云南、陕西、甘肃等地,已实现离境退税“即买即退”口岸离境互认办理。例如,境外旅客在重庆离境退税“即买即退”商店购物退税后,可以自行选择从成都天府国际机场、昆明长水国际机场、西安咸阳国际机场、兰州中川国际机场等完成退税核验后离境。

The experiment methodology left me dubious about the kind of point they wanted to make. Why not provide the agent with the ISA documentation? Why Rust? Writing a C compiler is exactly a giant graph manipulation exercise: the kind of program that is harder to write in Rust. Also, in a clean room experiment, the agent should have access to all the information about well established computer science progresses related to optimizing compilers: there are a number of papers that could be easily synthesized in a number of markdown files. SSA, register allocation, instructions selection and scheduling. Those things needed to be researched *first*, as a prerequisite, and the implementation would still be “clean room”.
