Currying is a well-known (in functional languages) technique of transforming a function that takes multiple arguments (or an n-tuple of arguments) in such a way that it can be called as a chain of functions each with a single argument (partial application).

I propose to add its support into dart. Dart could implement them scala-way to keep both named / optional params and currying:

a = function(params1)(params2)(params3) {
  return params1 + params2 + params3
}

a(5)(6)(7)

The Function interface is empty which is silly. It should have a method on it to return a partially applied function just like Function.bind() in JS.

https://developer.mozilla.org/en/JavaScript/Reference/Global_Objects/Function/bind

var addOne = function(a, b) { return a + b }.bind(1); // This should work in Dart
