Shorthand for curried functions

[copumpkin]

I love partial application, especially in the presence of HOFs, but especially with the long syntax for lambdas it's currently pretty heavyweight to write those. Even if the syntax were more lightweight, I believe the following could be quite nice:

local foo(params1)(params2) = ...;

as shorthand for:

local foo(params1) = function (params2) ...;

Given that we already have the local foo(params) = ... as sugar for local foo = function(params) ..., it seems like iterating the current rule for each group of parentheses would be a nice generalization of the syntax. Same would apply to object "keys", as well as anonymous functions.

This looks quite unintrusive and it's nice that the definition syntax still resembles the calling syntax.
