Hey, I love Rust too. But Rust feels so... restrictive. I mean you cannot add perform i8 + i32! Neither can you do Option<i32> (Some<i32>)+ i32! This is intense! Of course, the result = explicit conversions everywhere which makes itself harder to read.

Then again stuff like 22/7 is allowed. I wonder why didn't it choose to be strict and prevent the truncation.

Also suppose you are doing some procedural/linear-imperative style programming.

let a = 15;
//...
let x = &a;
//...
let y = &a;
//...
//Now you want to change a
//damn I have to go back and change mut a. Fair enough, let's do it.
//Then you realize you may have to change the mutability of x and y accordingly
let x = &mut a;   //definately out of the table -- Risk of data race or dangling pointer

I mean these are not bad practices but these make it hard for a new comer to get into Rust. Specially if you are coming from a very tolerant language like Python or D etc.

"Hello world".println!; //won't compile
For fuck's sake, what's the point of UFCS then :(

All you need to do to is to wrap the borrow in a scope:

let a = 15;
{
let x = &a;
//....
let y = &a;
} // <- borrows end here
/// Now you can mut borrow
let x = &mut a;

Last time I checked:

No SIMD
Removed ? : operator
No ++ and --

Is rust still retarded? I want to like it, but it feels like those python PEP-8 shills that enforce their preference on you and tell you to treat it like the law.

I wanted to use Rust once
But it turned out it didn't have a basic "specify timeout in seconds" option with network requests in the standard library
People told me "well it's not ready yet" even though the language version was clearly 1.0
So I dropped Rust and never used it again since

this is my Rust story

if let is more sophisticated actually

lmao, now you know why python is a bad teaching language

the fact that it exists
