You mean using static this as follows?:

module myMain;

private
{
    string function(string)[string] callbacks;
}

static this()
{
    {
       // do something like this:
       //
       // auto u = __traits(getFunctionsByAttribute, "MyUDA")
       // foreach (myFunction; u)
       //    callbacks[myFunction.GetAttribute("MyUDA").Name] =
myFunction
    }
}

void main(string[] args)
{

    if (args[1] in callbacks)
    {
       callbacks[args[1]]("myString");
    }

}

That's also possible... but how can I find all functions with 
MyUDA?
