Is it possible to write a function like this:
zipn n list_1 list_2 list_3 ... list_n
which implements zip3 for n=3, zip4 for n=4 etc.? Looks like variable number of arguments are possible, like printf shows, so a general zipn should be possible, too. If it is possible, why there are functions like zip5 and not just zipn?
