Now that callable() is back in 3.2, we may replace hasattr(obj, '__call__') with callable(obj).
The built-in function is easier to read and gives better performance than attribute lookup.
$ ./python -m timeit "hasattr(None, '__call__')"

$ ./python -m timeit "hasattr(str, '__call__')"
1000000 loops, best of 3: 1.3 usec per loop
$ ./python -m timeit "callable(None)"
1000000 loops, best of 3: 0.299 usec per loop
$ ./python -m timeit "callable(str)"
1000000 loops, best of 3: 0.369 usec per loop |
