But changing the property of a name (this name can not be rebound) is a big shift in what names are about in Python -- and I don't think a good one. And what's the use-case, really? beyond the use case for all sorts of static typing... in case it's not obvious: -1 -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.bar...@noaa.gov
