I'm not aware of any such feature. You can set up calculations on the 
function call and the calls can be recursive.

It's therefore possible to use select to use one part of a written 
function to set some values plus a usePartTwo flag, say, which would 
then be used to call the same function again. The flag causing the 
second - non-reursive - part of the function to run with the calculated 
values/vars being passed in on the recursive call.
