It is exactly the same as with your variables in your former thread. As 
you store objects in variables, and functions are objects, and you can 
store any values within objects:
  Use objects!

They work as maps. Surely you already know accessing object propertys 
with the dot syntax:

  var o = {a:1:, b:3};
  o.a; // 1

But you can also access them with bracket syntax:

  var propname = "b";
  o[propname]; // 3

So you will use a object for your problem, where you can store any 
values and even functions:

  var myfn = function(params) { <body>; };

is also a valid way to store functions. Of course this one has no "name" 
(you can't set names of functions), but you can easily call it with

  myfn("something");

That makes no sense. Why should you want to "name" a internal function, 
which you never will see, and which is called inside the global 
function? Just use

  function main_function() { // no "param"
     return alert(document.title);
  }
