Hi there,
I've question concerning handling of hash value vs portability. Is
sage
developer guide manual one can read:
Here is the definition of __hash__ from the Python reference
manual.
Called for the key object for dictionary operations, and by the
built-in function hash(). Should return a 32-bit integer
usable as a
hash value for dictionary operations.
However with ipython (on a 64 bits machine):
In [1]: hash(None)
Out[1]: 140504985179472
which definitely does looks like a 32 bit value.
Just checking: you meant "does *not* look like", right?
