New submission from Ram Rachum <ram at rachum.com>:
I have just opened the same issue on CPython, and it was closed as a limitation
of the implementation: http://bugs.python.org/issue21444?
@ok_message=msg%20217957%20created%0Aissue%2021444%20created&@template=item
Maybe Pypy-dev would like to implement this.
I want to use big numbers for an object's length, but currently Pypy doesn't
support this:
Python 2.7.6 (394146e9bb67, May 08 2014, 18:18:57)
[PyPy 2.3.0 with MSC v.1500 32 bit] on win32
Type "help", "copyright", "credits" or "license" for more information.
>>>> class A(object):
.... def __len__(self):
.... return 10 ** 100
....
>>>> a = A()
>>>> len(a)
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
OverflowError: long int too large to convert to int
Same thing happened on Pypy3:
Python 3.2.3 (d63636b30cc0, Jul 30 2013, 07:02:44)
[PyPy 2.1.0-beta1 with MSC v.1500 32 bit] on win32
Type "help", "copyright", "credits" or "license" for more information.
And now for something completely different: ``it's beautiful: very
rectangular
and yellow''
>>>> class A(object):
.... def __len__(self):
.... return 10 ** 100
....
>>>> a = A()
>>>> len(a)
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
OverflowError: long int too large to convert to int
