Ted,

It's not necessary in this case, any references to myFun in the Module 
are scoped to the package aaa already as long as myFun's declaration is 
after the Begin[], which I can't tell since you elided code.

If you are using anonymous functions #0 refers to the function itself 
and can be used for recursive anonymous functions.

Regards,
	Ssezi
