x = if y > 5 { "foo" } else { "bar" }

  In what language is that valid syntax?

    This is valid rust. I don’t know if there are more languages with this feature

    This is Rust syntax, but there’s similar syntax in Haskell

  Never forget your roots

  (setq x (if (> y 5) :foo :bar))

  I honestly can’t see how this is more readable than

  x = (y > 5) ? “foo” : “bar”

  I get that it’s a syntax that needs to be learned, but it’s just so clean and concise!

    Because it can be done for multiple lines too. And you can do else-if too. Also, “if” and “else” is more recognizable than “?” and “:”

    x = if y > 5 {
        println!("Y was over 5");
        z + 5
    } else if y < 0 {
        handle_negative_y(y);
        z - y
    } else {
        println!("<WARN> unexpected value for y"}
        0
    }

    What I like about using if and else for that is that you’re already using those keywords for branching in other parts of the code.

    Though my least favorite is probably Python’s:

    x = "foo" if y > 5 else "bar"
    

    It just seems backwards to me

      Because Python wants you to read it like English: English:

      x is “foo” if y is greater than 5, else it is “bar”

      While Python’s version does feel a bit backwards, it’s at least consistent with how list comprehensions are set up (they can also feel a bit “backwards” imo)

        List comprehension is another thing I don’t like about Python :)

        There’s more of those, but one thing I do like about Python is that I get paid for writing it, so I try not to complain too much
