I know a lot of you may like case insensitive languages, but it just feels weird for me. And there is the "nim" language which makes no distinction between CamelCase and snake_case.
Another thing to get used to is the ability to include characters in names that you normally can't, e.g., - and ?.
I've never seen a language with such a variety of built-in data types (e.g. coordinates, tags, email, url, issues). There's support for IPv4 numbers as a base type (tuples) but I can't tell if there's support for IPv6, which shows the trouble with this approach for the language maintainers.
What does a type being built-in do for you extra? In ES6 you can define a template string builder which you could name, for instance, ipv4, and then when you want an IPv4 address literal you say ipv4`192.168.0.1` and get your object. Are there other benefits besides a literal syntax? (Not to slag on Red. One advantage I can see is avoiding the call at runtime to the ipv4 function.)
Red doesn't have all types in place yet (e.g. date! is coming, and maybe an @ref type, among others), but can still load the following:

REBOL was first built by Carl Sassenrath, who is probably best known for his work on the Amiga operating system. REBOL was cool, but happened when a half dozen similarly cool languages sprung up that also had the feature of being free and open source (while REBOL was proprietary and cost a little money). REBOL had some novel ideas, and some shortcuts for some particular types of development making for strikingly conc…
Please give Red a look. It can run like Python or can be made compiled AOT to a tiny binary using a C like systems language that runs fast. You can call Red from C and possibly vice-versa (not sure bout the latter). It has an awesome REPL, amazing GUI DSL, is homoiconic like lisp for easy macros, and is OS/free. I'm not sure where this couldn't be used as it can be both super high level or very low level.

Ill add they have Red/System for low-level. Some kernel or server coders should try putting some code through it to see how it does.
I hope this trend of Colour named programming languages continues. I would maybe choose Cyan, red sounds too professional :P

I'll add to my reply, because this is a really good question.

Fair enough, even if it is great, it won't have 30 years of optimizations like some C compilers, but hopefully it is still really fast.

That does look handy! I guess there must be a tradeoff in having your text default to meaning plain words if you mess up the syntax? Versus hopefully getting an error in the ES6 case.

I read their about page and their newest post. It was a lot to take in. It was concerning that all the screening had that windows look and feel. I am kind of excited to try something so large in scope and so different, but no Linux support would kill it before I even downloaded it.
Linux support is just the beginning. Soon you'll be able to compile for iOS, Android and other platforms.

The compiler doesn't optimize at all right now, but aims for simplicity. There was an article some time back about the best switches to use for most C compilers: compile for size. It often gave some of the best performance IIRC, the rationale being better cache use on chips.
