After playing around a bit I did find one difference in
the errors they can create.
>>> def count():
... yield 1
...
>>> apply(f, count())
Traceback (most recent call last):
File "<stdin>", line 1, in ?
TypeError: apply() arg 2 expected sequence, found generator
>>> f(*count())
Traceback (most recent call last):
File "<stdin>", line 1, in ?
TypeError: len() of unsized object
>>>
That led me to the following
>>> class Blah:
... def __len__(self):
... return 10
... def __getitem__(self, i):
... if i == 0: return "Hello!"
... raise IndexError, i
...
>>> blah = Blah()
>>> len(*blah)
6
>>> apply(len, *blah)
Traceback (most recent call last):
File "<stdin>", line 1, in ?
TypeError: len() takes exactly one argument (6 given)
>>>
Is that difference a bug?
