> Yes, I can, e.g. by implementing deferred deallocation, which is a primitive GC form.

sounds more like a form of manual memory management

as a programmer you know and you can even control it by designing the appropriate scope and moving between scopes

> You lose nothing when going out of scope with GC.

actually, you don't know

and yet whether or not other work is being done currently is in your control, thus predictable (unless you chose to give control out of your hands e.g. by introducing two threads racing against each other); same regarding the subset

a GC still won't run at the end of the scope - it will run at an unknown time and do an unknown* amount of work at the times it is running.

* subset of all allocations until it runs

if the arc is the last: the data structure is destructed and deallocated + atomic check

if the arch is not the last: atomic check

no, it is not. A gc won't run at the end of the scope when the reference is droped. And if it runs, the amount of work is unknown.

the work is predictable and the amount not arbitrary

> I'm being downvoted, but honestly, is anyone always testing their software while swap is active?

Yes, not only is my system using swap 100% of the time, but I am working on and using an application (Rust) which often is used during a high demand of swap and expected to run reliably.

why upgrade every 3 years when there are 7 years of updates?

the CCG isn't from the committee, but from Bjarne Stroustrup and Herb Sutter.

Bjarne is often in disagreement with the committee

So far I have broken every Linux distro I used except NixOS.

And if I were to break it, i could just reboot into the previous system snapshot.

And I haven't read 1000 pages of docs - from my experience id doubt it even has that many docs.
