[sf-lug] [PYCLASS] Session 3: Monday Oct 6

   good points! 

   a very crude iterative tool is provided 
in the functions that take function names 
and then repeat them some specific number 
of times. 
   would have been interesting to explore 
a do_twice() function that can be called 
recursively, which would handle (powers of 
two) times (doing something) repeatedly. 
you want 13? somehow combine 
do_twice(depth = 3) with do_twice(depth = 2) 
with do_once(). 
   not that i've coded it.
