[New-bugs-announce] [issue10356] decimal.py: hash of -1

[Stefan Krah]

New submission from Stefan Krah <stefan-usenet at bytereef.org>:

When the __hash__ method is called directly, the hash of -1
is -1:

>>> from decimal import *
>>> Decimal(-1).__hash__()
-1
>>> hash(Decimal(-1))
-2


I've a patch, which also sneaks in a ValueError.
