Why are RAII and garbage collection mutually exclusive?

While I think I understand the essence of the problem (i.e. a good GC keeps track of objects , not the area ), I don’t know enough about the subject to convince others.

Can you give me an explanation why there are no garbage collectors with deterministic destructors?

They are NOT mutually exclusive. Feel free to use C ++ with libgc (Boehm-Reiser-Detlefs collector). You can still use RAII, smart pointers, and manual deletion, but when you start GC, you can also just “forget” to delete some objects.

@ Indie's answer is that resources that are too late miss an important point: this is not a resource allocation release that is semantically critical, but rather a release order.

The reason GC does not seek to streamline the release is because ordering sorting is required to streamline requirements (dependencies) and an expensive algorithm.

Thus, the GC and deterministic cleaning are mutually exclusive, since the GC does all the cleaning, and it cannot afford to determine, but must rely on maximizing its effectiveness.
