You won't find such a new language. Most languages in use are already known to be Turing-complete. There is no new computation that "can't [be done] anywhere else [, except in some new language]".
It would be highly useful to give examples of things that are easier to do in your new language though.
Might as well just delete it.
Edit: How do I become a moderator here? Also, who is "we"? You and who else?
Downmod bot has got me in its sights.
Also, does this mean Dan does not run all of HN? Or do the sub-moderators just fluff?
Edit: Know where I can find the feed of user downmods?
Edit: I would also settle for a live stream of events; don't need the full history, if it doesn't exist.
When downmods serve to censor my content, they become my business. I don't know where you pulled 'upvote' from, though; I'm not sure there is much value in knowing them.
Edit: Someone is getting a feed of something...or they are just furiously refreshing this thread. hehe
If you haven't got something interesting and at least unusual to show off very early in your docs, it's something to think about in your language design.
Now, you may have to build up a bit, and I'd certainly say you shouldn't bend your entire language around the "one cool demo", but I do think your early docs should make a hard burn towards whatever it is that sets your language apart. It's just basic sales.
(Elsewhere in this thread ori_b says this was not an intentional release, so I mean this as general advice, not targeted at this case. I don't know how to prevent too-early linking on social media sites short of not releasing anything public, which has its own problems!)
I try to avoid replicating work.
If your language only has features from some other language, you are replicating work.
Unless of course you're trying to argue that the difference between python and javascript, for instance, is what each is capable of computing?
For example, Python has the concept of a decorator: https://docs.python.org/2/glossary.html#term-decorator. You can achieve the same thing in a variety of ways in JavaScript, but Python makes the concept of "a function that wraps another function" a central abstractions by providing syntax directly for it.

The discussion with aerovistae about computation came from their initial post:
>Unless of course you're trying to argue that the difference between python and javascript, for instance, is what each is capable of computing?
If we are talking about ideal machines, there is no argument to be made that there is a difference between what the two named languages are capable of computing.
In real life I am very happy to have very extended conversations explaining things to people who don't get it, but on the internet, it's really just not worth it. I'm sorry you have misunderstood so much of this thread.
This is about how programmers can express themselves and reason about code. Not many people would choose to write their CMS in assembly.
You read my comment way too literally. I did not mean that a new language should have a feature that can literally not be done anywhere else. I meant: what are the uncommon features? What sets this language apart from the (dominant) other langs?
As someone else pointed out, in golang this would be goroutines or channels or golang's approach to composition vs inheritance. You can certainly implement those in another language, but they're not first-class features in most other langs. Put together, those elements give golang it's characteristic flavor.
For this new lang, I'm interested in learning (as early in the docs as possible) what sets it apart from C, C++, golang, python, ruby, JS, haskell, erlang, D, etc. The hello world example teaches the reader something, but it's not the thing a person first landing on that page probably cares about.
And going back to my original statement, there's lots of things that are still missing from programming langs and associated ecosystems. Just look at JS, and how even today people are still furiously trying to extend it and work around it just to build simple reactive websites.
I think the important thing is to find the new things, but to realize that they aren't really new, just different ways of using the old. All of the languages you listed are really just specialized, assembly, or other, programs. Yes, most of the hard work has been automated away, but it's still there.
I like JS because it can be extended (though it can be very difficult to keep track of). I think there was a workaround phase when the VMs/interpreters/machines were slower, but pretty much everything can be compiled to JS these days. You don't even need to do that though, as JS embeds first class functions, so pretty much anything is within easy reach.
