It's probably not intentional, but I find that comment vexing.  For 
example, I have Mark Lutz "Programming Python" in my hands and there's 
long lines everywhere and I consider this code properly commented and 
maintainable.  Even if I'm relatively new to python, I'm an experienced 
programmer and I think I can measure and not abuse of long instructions. 
  Sorry to overreact ;)

Come on, that is not obscure at all.  I agree your solution is more 
scalable but in that case it is intended to be not needed since the 
lambda is only used to make a method callback.
