has_key exists only for backwards compatibility; the 'in' operator is
preferable.
$ python -mtimeit -s'd={}' 'd.has_key(23)'
1000000 loops, best of 3: 0.289 usec per loop
$ python -mtimeit -s'd={}' '23 in d'
10000000 loops, best of 3: 0.139 usec per loop
Why consume twice as much time with no advantages whatever?!
