| 9 * SUMMARY: Applying Function.prototype.call to the Function object itself | |
| 10 * | |
| 11 * | |
| 12 * ECMA-262 15.3.4.4 Function.prototype.call (thisArg [,arg1 [,arg2,…] ] ) | |
| 13 * | |
| 14 * When applied to the Function object itself, thisArg should be ignored. | |
| 15 * As explained by Waldemar (waldemar@netscape.com): | |
| 16 * | |
| 17 * Function.call(obj, "print(this)") is equivalent to invoking | |
| 18 * Function("print(this)") with this set to obj. Now, Function("print(this)") | |
| 19 * is equivalent to new Function("print(this)") (see 15.3.1.1), and the latter | |
| 20 * ignores the this value that you passed it and constructs a function | |
| 21 * (which we'll call F) which will print the value of the this that will be | |
| 22 * passed in when F will be invoked. | |
| 23 * | |
| 24 * With the last set of () you're invoking F(), which means you're calling it | |
| 25 * with no this value. When you don't provide a this value, it defaults to the | |
| 26 * global object. | |
| 27 * | |
