Why would one choose this:

  var int_item = $(Int, 5);

over this:

  int int_item = 5;

What am I missing?

Well with the var option you do something like this:

var item = $(Int, 5); ... code ... item = $(String, "5");

Not that you want to do that all the time but it is a way to implement duck typing

A better example for duck typing would be something like:

var my_func(var int_or_string, var int_or_obj) { ... return int_or_string_result; }

Simplifies certain operations, complicates debugging. Great for small scripts though.
