As requested by Neal Norwitz, some benchmarking (all times
in usecs per loop):

./python -mtimeit 'def foo(*args): pass' 'foo()'
As tuple: 1.56
As list:  1.7

./python -mtimeit 'def foo(*args): pass' 'foo(1)'
As tuple: 1.75
As list:  2.04

./python -mtimeit 'def foo(*args): pass' 'foo(1, 2)'
As tuple: 1.87
As list:  2.15

./python -mtimeit 'def foo(*args): pass' 'foo(1, 2, 3)'
As tuple: 1.95
As list:  2.3

./python -mtimeit 'def foo(*args): pass' 'foo(1, 2, 3, 4, 5,
6, 7, 8, 9, 10)'
As tuple: 2.67
As list:  2.97
