Packing a list of lists with struct.pack()

the *arg form treats each value in the arg sequence as a separate argument.
for example,

    arg = 1, 2, 3
    function(*arg)

is the same thing as

    function(1, 2, 3)

when used with a generator expression, *(genexp) simply fetches the arguments
from the generated sequence.

(note that struct.pack expects a format string plus N additional arguments, not
a format string and an N-item sequence)
