UNCLE! (was Re: eq and hashing (was Re: [plt-scheme] How to make unit functors?))

hi,

i was just reading the python-dev newsgroup and came across a
discussion there that might be relevant to this thread.  there were
two interesting points.  first, python hashes are consistent across
programs, not just within a single execution, and this seems to be
considered a significant feature.  second, the discussion was prompted
by someone posting a claim that poor hash functions allowed denial of
service attacks (i should add that no-one seemed that worried about
this).

the most interesting response is probably this one:
http://aspn.activestate.com/ASPN/Mail/Message/python-dev/1655348 and
from there you can access the whole thread.

cheers,
andrew
