The question in language design is never 'could we do these things 
before'. The answer is obvious: yes our CPUs are turing complete; we can 
do anything. The question is; how would we like to do them?

So do you think the new head/tail unpacking features in python 3 are 
entirely uncalled for? I personally quite like them, but I would like 
them to be more general.
