better support for curry

[co-dh]

add = (x) -> (y) -> x + y 

add 3 4 will be parsed as add (3 4) , which apply 3 as a function to 4 . the only way to get parsed is :

add(3)(4)

which has too may braces.

I suggest to change the syntax, so white space is treated as application.

add(3) 4 and (add 3) 4 both do what you want. White space is treated as application, it's just right-associative, not left-associative, which makes way more sense than the alternative.

[co-dh]

I don't agree right-associative makes more sense than left. suppose you are using CPS programming, as in http://en.wikipedia.org/wiki/Continuation-passing_style you'll find left-associative is a must. Also CPS is used a lot in node.js

You do realize that changing that would break practically any CS code ever written, right?

Thanks. Interesting. personally I prefer coffeescript's syntax.

If it's a mistake, the early we correct it, the better. Anyway, didn't coffee script breaks all javascript code that already written? Also, a simple convert could be write to convert right associative to leve associative.

It's not a mistake, just a design-level decision. I believe coffee's wide audience is a little too wide for such a change. Have a look at this search of projects on github which use coffee-script ;)

If you want Haskell, you know where to find it. ;D

In all seriousness, though, I think left-associative is a better fit for a language that means to retain JavaScript's semantics. The Wiki has a big list of other languages that compile to JavaScript, including a few versions of Haskell and OCaml, that might be a better fit for your needs.
