sirico comments on Infallible Code

As we're posting examples I'll add how lovely it is in Elixir. Elixir def not putting the fun in programmer memes do. One reason I picked it because I can't be trusted to not be the meme.

def is_even?(n) do
  rem(n, 2) == 0
end

I mean, it would be almost this exact thing in almost any language.

fn is_even(n: i64) -> bool {
    n % 2 == 0
}

even n = n `rem` 2 == 0

def is_even(n):
    return n % 2 == 0

etc

Personal preference, but elixir just strikes a balance that doesn’t make me feel like I’m reading hieroglyphs so I’m actually happy to see it praised.

I would have preferred for the function to be called mod, since it's the modulo operation, which in math is represented with a percentage or "mod". Most programming languages use a percentage because of that, so do a lot of calculators.

Yeah, I agree that Elixir is a fine language for some tasks. I personally find the readability somewhat average, but it's very maintainable (due to how it enables clear program structure), the error handling is great, and the lightweight process system is amazing.
