Discussion on: The Coolest Programming Language Features

Oh, so this is pretty cool. Let me try to understand it better. Instead of writing a constructor with ten parameters, you can expose properties that can be set with an extension lambda?

yes, basically, but it has a lot more uses!, for example there is a library that allows you to write html using extension lambdas and it looks like this:

html {
  head {
    title { +"Page title" }
  }
  body {
    h1{ + "Cool article" }
    p { +"article content" }
  }
}

they have the same flexibility as normal lambdas but with a lot less boilerplate

[Jeremy Grifski]

Wow that’s elegant. I imagine you get the added benefit of type checking and whatnot, right?

[cout970]

Yes!
