I am learning Rust. One missing C++/Java feature is function 
overloading. One of the explanations of this decision is that "function 
overloading is an anti-pattern", because, among other things, "it leads 
to less readable and understandable code".

This surprised me because I consider it very useful. I really hate 
having to code multiple functions with different names and almost the 
same functionality. I suffered this in Python (its solution based in 
decorators is not the best), and also in Typescript (its solution based 
in several prototypes for a single function is really awful).

What is your opinion about the function overloading as an 
"anti-pattern"? is it?

Disclaimer: "Overloading" where only types differ (but the number of 
parameters are the same) is possible in Rust using generic traits, 
something like the following:

struct MyPrinter;

trait Printer<T> {
     fn print(&self, value: T);
}

impl Printer<i32> for MyPrinter  {
     fn print(&self, value: i32) {
         println!("Value: {}", value);
     }
}

impl Printer<&str> for MyPrinter {
     fn print(&self, value: &str) {
         println!("Value: {}", value);
     }
}

fn main() {
     let foo = MyPrinter;

     foo.print(10);
     foo.print("Hello");
}
