Even if they are used in everyday code, the use is usually hidden -- i.e. when a user subclasses from an ORM model class, they are using metaclasses, but they don't have to know that. That is -- they fall into the category of stuff that should only be used by library/framework developers -- and, in fact, the whole point is to make everyday code easier. In fact, the number of developers that need to write/debug metaclasses, context managers, decorators, is far fewer than the number of folks that USE those things. So the standards are very different. -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 [email protected]
