The behavior differences between dicts and sets is already surprising to many users, so we should be careful not to make the situation worse.
It's a nice to have, but other than the fact that we all used to use a dict when we really wanted a set before set existed, I'm not sure the connection is there to a layperson. A mapping and a set type really don't have much to do with each other other than implementation -- anyone that isn't familiar with python C code, or hash tables in general, wouldn't likely have any expectation of them having anything to do with each other. -CHB -- Christopher Barker, Ph.D. Oceanographer Emergency Response Division NOAA/NOS/OR&R (206) 526-6959 voice 7600 Sand Point Way NE (206) 526-6329 fax Seattle, WA 98115 (206) 526-6317 main reception Chris.Barker@noaa.gov
