ActionScript 3.0 :: Map Data Types To Custom Types?

Consider the following function:

Code:
public function foo(bar1:int, bar2:uint, bar3:String, bar4:Boolean):void{}

What I want is to have the different types of data represented by custom named types which are essentially representing the original data types. I other word, I would like to proxy the data types and have a valid function as following:

Code:
public function foo(bar1:PAR_Bar1, bar2:PAR_Bar2, bar3:PAR_Bar3, bar4:PAR_Bar4):void{}

so PAR_Bar1 would proxy the `int` data type, PAR_Bar2 would proxy the `uint` data type, so on and so forth.

The reason I need this is because I'm using a debugger with a GUI that can run methods and allows changing function parameter values in real-time, the issue is that the debugger can't tell me what parameter I'm changing, it only displays the data type of a parameter. So if I need to change 10 different parameters all of type int, the debuggers display all of them as int and not by their names.

I think that if I use proxy types I can easily differentiate between parameters.

So, my question: Is it possible to proxy data types? I mean map specific data types to custom data types that would represent the base data types?
