I would argue `by` and `data` are the two most powerful keywords from any of the modern languages (~last 10 years) maybe next to `go`.

You should check out the "with" keyword from elixir, (but the #1 all time best elixir feature is the |> (pipe) operator combined with IO.inspect)...

IMO `async/await` (C# / JavaScript), `defer` (Go), and `guard` (Swift) have changed the structure and flow of programs and are commonly used in their respective languages. Why do you believe that `by` and curiously `data` are so powerful?

What does `data` do, and in which language?

[letientai299 → ngrilly]

I think he means `data` class in kotlin.

Yes, it looks like this. Thanks!

Everything old is new again.

I was considering `data` specifically in the context of the JVM. I understand we’ve had structs for ages but the concept of anything other than a reference is so terrribly foreign to the JVM it has made so many really shitty programs noticeably less shitty.
