ActionScript 3.0 :: How To Interact With Interchangeable Function In Library

I have written a library. This library has a function that has an argument being a function.
Actionscript Code:
//(its static)class MyClass {
function foo(method:Function):void;}

I have created over 30 functions that are acceptable as an argument to that function. But they raise the file size by 6kb alone! So I've found that most people won't use more than an average 6 functions in a program, so why use all that extra space? I am trying to find a way to have all of these functions available in their own 'namespace' so that compiler only puts in the functions that are referenced specifically. I also want a way that I can still force all of them to be compiled in (like a manifest).

Below, is how these functions are currently setup:
Actionscript Code:
class MyClass {
function foo (method:Function):Array;}class Methods {
function bar1 (param1, param2):void;
function bar2 (param1, param2):void;
function bar3 (param1, param2):void;
function bar4 (param1, param2):void;  etc...}

I really just want personal preference input here. If you were using a library that was built this way, how would you want to interact with these interchangeable functions?

Options:

1. Package Level Functions: Make them all package level functions. You would import one at a time.
Actionscript Code:
package com.net.methods {
function bar1 (param1, param2):void;
}package com.net.methods {
[Code] .....

To cover the manifest problem, I could create a class that imports all of the functions, then all you have to do is reference that class in any class.
Actionscript Code:
package {
import com.net.methods.bar1
import com.net.methods.bar2
import com.net.methods.bar3 
import com.net.methods.bar4 

2. Grouped by Functionality: Another idea is to group the function by commonality.
Actionscript Code:
class Xbased {
function bar1 (param1, param2):void;
function bar2 (param1, param2):void;
function bar3 (param1, param2):void;
[Code] .....

3. One Class, One Function
Lastly, I guess you could make a separate class for each function. Maybe this would give me greater flexibility in the end but that is unclear.
Actionscript Code:
class bar1 {
function execute (param1, param2):void;
}class bar2 {
function execute (param1, param2):void;
[Code] .....
