is self anything more than syntactic sugar in rust? I've gone pretty deep into that part of the language and I can't think of anything about self that can't be stated with functions that take foo as an argument. i'm definitely not a fan of self in other languages, but rust's take on self is very different. but i'm coming from higher level languages so i'm curious what the c++ take on this is.

ratbert90 posted:Lots of languages get by just fine without needing a self or this syntax. yeah but if this is gonna be your foundational argument for avoiding a language it needs to be something other than a avoidable syntactical shorthand. and self in the context of rust is really not the same as this in javascript or java, because in rust you're not dealing with an object system. it's literally just syntactical sugar.

well there's one case i can think of where self has different semantics: you need it you want to do dynamic dispatch. which is maybe your objection to begin with?

gods yes, give me explicit scoping any day it’s one of the best things about Smalltalk and Objective-C only in Common Lisp and Dylan do I not feel its lack when writing or especially when reading code, and that’s because they do full multimethod dispatch instead of messaging

Honestly, (1) program in more different languages, (2) compare and contrast the differences in how programming works in those languages and then (3) look up the proper technical terms for those differences.

I've literally never programmed anything more than pasting together powershell poo poo from stack exchange. Mind you, I don't especially want to be a programmer but I'd like to at least be able to go  and fake it like I sort of can with processors.Is there like an equivalent of this but for software?  E: I was so sad when I found out this guy was a right-libertarian fucko.

Slurps Mad Rips posted:rust is cool, but I feel like I’m fighting api decisions more than anything else there's been a lot of discussion about stdlib decisions lately. honestly i dont have enough experience with writing low level code to have a strong opinion. removing the Zero type annoyed me. more than anything i think the language just isn't ready to replace C/C++ and so when people come from C/C++ and find they actually cannot do everything they want to do, they're reasonably a bit upset. sure, you can write unsafe rust, but writing unsafe rust requires a strong knowledge of how the compiler is going to gently caress with your memory, i really don't think it's the same as writing C. but that may just be me: i've only started with learning C in the last month or so. however, as someone coming from a high level language, it's really fantastic. i get 90% of what C/C++ give me and I get everything I want from HLLs.

implicit this for member variables sucks (in C++, java, and C#) because you will get variable name collisions and you can get confused about scope it's such a problem that lots of programming conventions will make internal member variables be prefixed with strings like "_" or "m_"

the other criticism you could make against self/this is that rust shouldn't have had member functions in the first place and tried to be more like a functional programming lang for better or for worse, Rust intentionally wanted its syntax to be more familiar to the mainstream and not turn off people by making its syntax look like haskell or ml or whatever

tail call elimination is apparently an unsolved/potentially unsolvable problem w/r/t lifetimes/borrowing so fully embracing functional would probably be a bit weird. but i agree. i want the language to succeed since i'm investing in it. member functions are probably the part of OOP people actually want, (even though they're orthogonal to OOP), and rust provides them without most of the bad stuff. it seems like a reasonable tradeoff to me.

It's about learning 3 languages and their key ideas (SML, Racket and Ruby). it forces you to think about a lot of stuff you never really think about in introductory p-lang courses (typing, mutability, scoping, dispatch etc) I don't recall if it goes through historical stuff like lisp-2 namespaces, but it definitely puts you into a place to understand what tef is rambling about

so i'm working on generating interrupts for my emulator now. i can implement it synchronously and i'm sure it will work fine, but i'm very tempted to run the cpu in its own thread and send interrupts to it. this seems to better match how the machine would actually work. am i right here or am i just making excuses to play with futures?
