closures

this thread is dedicated to javascript's most important innovation: the concept of functions that capture their lexical environment


var arr = [];
for (var i = 0; i < 10; i++ ) {
  arr[i] = (function (i) {
    return function () {
      return i;
    };
  })(i)
}
beautiful!

i'd like to see your language do the same thing more elegantly!
