[issue10356] decimal.py: hash of -1

Are there situations where this is a problem?

I don't think that there's any requirement that the __hash__ method for a user-defined Python type not return -1.  (It's also allowed to return values outside the range of hash values;  these get automatically rehashed to values within the range.)
