alt Hacker NewsHave you ever used other (modern) programming languages ?
In a lot of languages, you achieve the same with 1 line of code. It's not about familiarity, it's about the fact that it's a long and convoluted incantation to get the name of an enum.
Why do I have to be familiar with all those weird symbols just to do a trivial thing ?
Update:
Zig:
const Color = enum { red, green, blue };
const name = @tagName(Color.red); // "red"
Rust:
#[derive(Display)]
enum Color { Red, Green, Blue }
let name = Color::Red.to_string(); // "Red"
Clojure:
(name :red) => "red"

C++:
enum Color { red, green, blue };
auto name = to_enum_string(Color::Red); // "Red"➕ show 1 reply
And what if you want to implement something like Rust's "derive"? That is what the article shows.
As far as I understand you would have to mess with individual parser tokens in Rust instead of high-level structures like "enum" (C++ reflection). It would be much, much uglier to implement anything like "to_enum_string" in Rust as you would have to re-implement parts of the compiler to get the "enum" concept out of a list of tokens.
