i'm curious when/if we'll see a serious garbage collected implementation of c++ also smoke piff get piffy

Not sure if this counts as 'serious', but it is a C/C++ garbage collector: http://www.hpl.hp.com/personal/Hans_Boehm/gc/ http://en.wikipedia.org/wiki/Boehm_garbage_collector It's used by Mozilla, Mono, irssi, Scheme implementations, etc. too.

There are conservative GCs, you can't get a real GC because the C++ type system is optional.

hotspots gc is fine. gc pausing is one of those non-issues that greybeards bring up when they talk about savage optimizations they can only do in c. there are sometimes specific reasons to pick a different gc mechanism or to tweak the settings but those are only after you've actually determined theres a performance problem caused by gc which is almost never the case. its another case of guesswork theoretical analysis where autismals will try to pre-optimize the system instead of looking at the real world metrics. you are not writing perfect code that is somehow beyond the capabilities of the gc. you're either doing dumb poo poo like destroying and recreating the same objects over and over OR (and this is the case in 99.99999% of cases) you have a loving memory leak. fix the leak you shithead.

GC pausing is an issue as soon as you have any hard real time constraints (and some soft ones).

otoh many things are an issue when you have real time constraints

i sort of said this spread out across a couple of posts, but reference counting plus everything-is-a-table is a neat language model. only reference count on the table level, and encourage large tables rather than a billion atomic objects floating around. combines beautifully with column-orientation basically kx k/q is the holy land for scaling

sorry officer I rear-ended the other driver because someone didn't tune the GC of my braking system correctly and it skipped on the signal I sent

moving forward using all my mem allocating with you was never second best i saw the program crashing all around your stack never knowing who's right in the forum black i'll stop the world and gc with you

Surely not every last line of your codebase is performance critical Do the performance critical stuff in C, layer some plang interpreter on top of it and export your high performance primitives as a dsl i still think code where you don't explicitly qualify your types is needlessly obnoxious to maintain for anything bigger than like a college project though
