Some of this is a definite improvement over Lua, but I'm getting really tired of some of these cute little syntaxes showing up everywhere, like '->' and '=>' for creating functions, and what's with this:
! operator can be used to call a function with no arguments
Seriously?
I feel like people are coming up with these things just to be "different". Programming language syntax is a UI, and needs to be treated like one -- you don't make major changes to basic UI paradigms without convincing reason.
Edit: Maybe more to the point, you don't add random buttons to a UI that do non-obvious things. Language syntax should be self-evident and quickly readable, and shouldn't require careful parsing of individual characters.
If this were somebody's toy or research language, I wouldn't be complaining, but when a language is clearly being marketed as something people would want to use in the real world, I expect it to be based on real evidence and real experience, not just somebody playing around.
It's human readable as far generated code goes. It's not always practical to read (specially with classes), but you can if you have to. It's one of the philosophies behind CoffeeScript. As you can see its translation of OOP is verbose too, but readable [1], and the verbosity of the generated code is balanced by the power added on the CoffeeScript side.
My point/question was: it doesn't add a runtime or new libraries/routines, you can read the generated code if something goes wrong, so why wouldn't it be ok to use in production?
"Nice" is relative, I think the site is a colorblind monstrosity (it actually looks better when I invert the colors!), but someone clearly put some effort into it, as well as the reference manual, and there is no indication given anywhere that it should be treated as anything other than a serious entry into the world of production programming languages.
On the contrary, at the very top of the page, albeit in extremely poor contrast, it says "A programmer friendly language". That certainly implies the author considers it to be good for something other than "playing with new syntax".
