Key point being, similar to some random languages. JS and Python Syntax don’t fit a typed and compiled language at all.
Pretty syntax would probably be something like C, where not every single character already widely reserved for specific keywords (like !, ', =) is reused in completely random ways.
Ah yes I also found macro syntax like vec
what? what part of rust is ugly?
Literally every single bit of the syntax.
The majority of its syntax is very similar to many other languages. Can you give an example of a language with pretty syntax?

Ah yes I also found macro syntax like
vec![andprintln!(to be a bit jarring at first. However I don’t know if I would say that C’s approach to macros is any nicer, with it’s#definemagicBeing unable to give an actual example proves you’re just a foaming-mouth hater with nothing to contribute.
From the first syntax examples on Wikipedia:
fn main() { let foo = 10; // Suddenly, types are implicit now. A safe language should never have implicit types (now it's the (IDEs) implementations judgement which type that is. Combined with the variable shadowing "feature", this seems like a major clusterfuck. Now the IDE is the sole thing to tell you that you totally fucked up the logic, and both declarations/definitions (well which one is it? Would be nice to always have a direct KEYWORD telling you which type this fucking variable has. But no, the lazy piece of shit Rust 'programmer' left that as an exercise to the dear reader. Because in they just need to leave that part out instead of explicitly stating "I'm a lazy piece of shit" by *instead* typing 'auto'.) This is just Python-level BS. Yes, I also hate C++ for its auto keyword - but at least it explicit. println!("The value of foo is {foo}"); let foo = 20; println!("The value of foo is {foo}"); }fn add_two(x: i32) -> i32 { // That is, again, the syntax of Python. Why? Because Python is explicitly untyped. So having types be a *literal* afterthought is Ok. They're fully optional anywhere there. Now we're in Rust. They're sometimes optional, sometimes not, but they're always preferred. Yet, they're also an afterthought, seemingly. x + 2 // Implicit statements are bad. Very bad. They so much invite to glossing over stuff, especially when your brain expects to see something else. Also, having every statement ended with ;, except context blocks, but suddenly *not* having statements ending with ;, is fucking ugly (which is the entire point of this rant). It's completly inconsistent. Which in itself is a huge magnet for errors. }if x > 5 { // Now why would you leave the parantheses, which are a major contributor to readability, away. Or even allow this. Rust is just memory safe, like dozens of other mainstream languages, but continues by allowing, promoting and requiring hazardous practices. println!("value is greater than five"); }Now I’m slowly getting annoyed from typing on phone (at least in nvim), and my throat gets clogged with mucus again.
Remember, some of that are subjective preferences and opinions. And the core idea of Rust - fast but safe programs - is good, yet very obvious and not innovative at all, while the syntax and implementation (of cargo (yes I like to wait an hour for a simple webapp to compile because there aren’t binary crates and cargo just doesn’t multicore 99% of the time)) is subpar to something that’s hailed as the savior for everyone and everything by such a large cult.
Types are not implicit, they’re inferred by the compiler when there is no ambiguity about what the type needs to be. This is a huge benefit for refactoring code and reducing maintenance. I acknowledge that sometimes you might care to know the exact type of the variable, and sometimes that’s not as easy for a human to infer as it is for the compiler, but every decent IDE will provide inline type hints for you. Interpreting code by reading it in plaintext is an exercise in masochism.
Python is actually the opposite on this, and it’s one of Python’s worst characteristics. The type is unknown until runtime unless you annotate it, and then the annotation isn’t really enforced. It’s the worst of every dimension.
C++11 introduced auto, and now the community is split between “almost always auto” and “never auto”.
JavaScript needed a whole new compiled language (Typescript) to fix its type system problems, and Typescript is only an incremental improvement at best.
Rust has the best type system of any modern language by far. If you’re tripped up by not always seeing the type declarations then you’re either focusing on the wrong details in the code or you just need a little more practice. The key thing that needs to sink in for new Rust users is that the compiler is always providing safety rails. That means it’s no longer your job to verify that every aspect of the code is correct. You can relax a little and actually have something akin to duck typing without all the pitfalls that usually come with it.
In practice, type inference in Rust is not a problem since the language is so strongly typed. In fact, it is more strongly typed than both C and C++, and will force you to cast values explicitly in cases where C and C++ will happily mess up your variables without warning. The absence of type inference would also be a major pain, since nested types such as iterators can get quite complex and very verbose. If you’ve programmed using older C++ standards, then you know this pain
Average Rust code:
macro_rules! sum { ( $initial:expr $(, $expr:expr )* $(,)? ) => { $initial $(+ $expr)* } } fn remove_prefix<'a>(mut original: &'a str, prefix: &str) -> &'a str let mut up = 1; 'outer: loop {This is on the level of the esolang I made at 8 y/o, with random characters denoting random actions everywhere, at random positions.
It’s incredibly disingenuous to call this average Rust code and further erodes your credibility. I may as well point to hundreds of lines of preprocessor macros in a C++ header and call it average C++ code.
This is not what an average Rust developer is writing 99% of the time. If someone on my team submitted a PR with an implementation of
sumthat usesmacro_rules!I would almost certainly reject it.
