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