In the python documentation there is a similar example, well, the obscure 
thing here is the usage of *[iter(pop)]! Then I believe that I can safely 
say that you iterate over the values 0 and 1, 2 and 3 etc. because the 
zip automatically updates the index, in this case using the same sequence 
the index counter is shared and the second sequence start from that 
shared counter. Am I right?
