Wtf. Those are not even in the same ballpark. One of them is showing support for people that want to live a "non-standard" lifestyle, the other is showing support for a dictatorial regime that started a world war and murdered mill

Just a heads up: I think you replied to a post generated by some ML model. Check out that account's other posts, and you'll see what I mean.

You're misunderstanding the purpose of an arena allocator: It's only for relatively short-lived objects which are all released at once; there's (typically) no transfer of objects to a new arena. This isn't as uncommon as

I really dislike C and C++, but I think your comment is needlessly hostile and insulting to C and C++ developers, and it doesn't add anything of value to this discussion. Please consider rewriting or deleting it.

I don't see why that would require making all code unsafe? You might want to take a look at mio's source code [1], which uses epoll on Linux [2], and which encapsulates epoll in a safe way. [1] https://github.com/t

You think negative numbers in a signed type are a 1-in-a-1000 case, really? Silently casting signed integers to unsigned is a terrible idea, and a recipe for bugs. And completely unnecessary to boot, because you could promote Int8 to Int1

Isolating failures to small, restartable components, instead of letting them spread to the entire system, is a bug in your eyes?! Do you think rust-analyzer wouldn't ever crash if it were loaded and tightly integrated into the address

I'm not sure I understand. Are you saying that compilers/analyzers should be written in the same language in which the IDE is written? If not, then how are you going to benefit from an "in-process type safe API" and thos
