Would reference counted classes by default be too much of a change? Is it a bad idea? Currently there a changes in the language where you can avoid the reference count, right?
Combination both the rc and the stop-the-world gc, for the cycles.

Currently there a changes in the language where you can avoid the reference count, right? Since classes are reference type, I think it can be done. If I'm wrong please explain why. Now, I think there might problems with existing code as there is no concern about the RC when classes are passed around. However, for new code this can be mitigated. In practice this would lead to RC classes while other structures would still be garbage collected. This would reduce the amount of garbage collected memory which could be beneficial. What I would find interesting is if this would enable deterministic destruction of classes. It's an interesting subject and could be a half way step to more a more versatile memory management. |

For deterministic object destruction, there's the
Isn't the exact same as real RC, but then you can use automem for C++ style reference counting if you want. |
