It's kind of funny that in c++ even the garbage collector is a dangling pointer XD

[EpicSnakes]

"The standard comitee is meeting in Hawaï each year" Definitly the best argument to improve myself in C++ and become an expert.

[RobertFisher]

Maybe it is just splitting hairs, but my understanding is that the standard was only trying to add minimal changes to the language/library that enabled garbage collection implementations to interact better with the language and give programmers the tools to help such implementations. It isn’t so much that “C++11 includes garbage collection that was never implemented” as much as “C++11 made implementing a garbage collector for C++ safer”. It would be up to a GC implementation (like the existing Boehm GC) to do the actual implementation and leverage the new C++11 GC features. (What I’m unsure about is how much the compiler would have to actually be involved with that.) Edit: I greatly appreciate that you cover this kind of stuff.

GC has no place in C++, unless as an optional library.

[marksilverman]

The title of this video sounds a poor attempt at trolling but it's legit.

[BenUK]

If GC had been implemented would we have still had deterministic destruction (As required by RAII etc) or more Java-like non-deterministic finalization? For me deterministic destruction is probably THE most important language feature in C++ over other languages.

[seancpp]

This is super interesting. Thanks for sharing Jason.

[homomorphic]

Anyone proposing garbage collection in C++ should be banished to Antarctica.

Every pointer I ever use is xor'd.

[Spongman]

notice that one of the 'Reply To' in the spec is 'Hans Boehm' of Boehm GC fame(?).

[UpstreamNL]

The first epsiodes that overflows a byte!

[mworld]

Garbage collection is only on Mondays here.

[Kazooie]

One important question comes to my mind why this is not implemented fully? Why many compilers has this as a no-op and not actually as a feature?

[rafalmichalski]

Hello how did you get this LeakSanitizer log ?

[perfectionbox]

why bother when we have smart pointers? Or was the gc going to defrag memory also?

[herrdingenz]

3:54 So now Hawai'i for you in 2021 :P

[lincolnsand]

Suggestion: could you do a video on new handlers?

[TheSulross]

if really want garbage collection then can go code it in Go or Java or C#

[vuongbinhan]

I think you have to have robust cross-platform runtime & build system before any garbage collector can be functionally implemented. For C/C++, that's pretty far-fetched, it's been many decades and build systems just keep becoming messier.
