1.11 + *
1.12 + * SUMMARY: Applying Function.prototype.call to the Function object itself
1.13 + *
1.14 + *
1.15 + * ECMA-262 15.3.4.4 Function.prototype.call (thisArg [,arg1 [,arg2,…] ] )
1.16 + *
1.17 + * When applied to the Function object itself, thisArg should be ignored.
1.18 + * As explained by Waldemar (waldemar@netscape.com):
1.19 + *
1.20 + * Function.call(obj, "print(this)") is equivalent to invoking
1.21 + * Function("print(this)") with this set to obj. Now, Function("print(this)")
1.22 + * is equivalent to new Function("print(this)") (see 15.3.1.1), and the latter
1.23 + * ignores the this value that you passed it and constructs a function
1.24 + * (which we'll call F) which will print the value of the this that will be
1.25 + * passed in when F will be invoked.
1.26 + *
1.27 + * With the last set of () you're invoking F(), which means you're calling it
1.28 + * with no this value. When you don't provide a this value, it defaults to the
1.29 + * global object.
1.30 + *
