Re: Proposal: Lua should have arrow operators

[Charles Heywood <vandor2012@...>]

I personally feel that while it is nice, it'll lead to ambiguousness. Haskell does it nicely: functions with multiple arguments essentially "return" a new function, so `x y $ z 1` would be like z(1)(x(y))` (I think it was Haskell...). Because Lua has only one function call for multiple arguments, I feel it's a tad bit weird.

It looks very functional. I like it. 
If it's not costy, it would be an incredible addition!

You can almost do that right now:

debug.setmetatable(0,{
        __bor = function (x,y) return y(x) end
})

print(math.exp(1) | math.cosh)
