Variables declared in outer function can not be cached (v1.2)

[jingwood]

Variables declared in outer function but used in inner function can not be cached so the following code does not work in ReoScript.

fun1 = function() { 
  var cached_var = 10;

  return function() {
    console.log('cached_var = ' + cached_var);
  };
} ();

fun1();

The result is that cached_var is null.

Functions will cache the call-scope where function was defined in. This issue has been fixed and planned to be available since v1.3.

Now overriding a function by 'apply' method will be available. (The original code of following sample was published in StackOverflow http://stackoverflow.com/questions/9134686/adding-code-to-a-javascript-function-programatically)

var t = debug.assert;

t( Function.prototype.hasOwnProperty('apply') );

var a = 0;

function fun1() {
     a += 10;
}

fun1();
t(a, 10);

fun1 = (function() {
var cached_function = fun1;
     return function() {

     // code before override goings here
     a += 5;

     cached_function.apply(this, __args__);      // use .apply() to call origial function

     // code after override goings here
     };
}());

fun1();                 // now fun1 is an override function
t(a, 25);               // a is 25
