I'm curious where your negativity is coming from, all of the comments you've written on this thread so far are negative.

Sorry I know I sound pretty negative, it's frustration about people pushing for languages that are clearly not ready and for some of them will never be.

You've got to realise that to a lot of people these languages are already ready. Nim coming closer to 1.0 is certainly evidence that it will soon be ready for a vast majority of users.

> None of Crystal / Nim have such a structure.

That's right. Not yet.
