Cunning? Well, you can define routine ID constants/variables at the top of the 
file, reference them in the middle and set them at the end. Even in C, it is 
ordinary programming practice to "#define function(parameters);" if it is called
before it is instantiated. It would be slightly more convenient to be able to 
call *before* it is defined, ut we are talking about an interpreted language! In
terms of coding, I think is is not too much work around at all.
