Did you run out of clever abbreviations after s/union_update/update/ or do you think that symmetric_difference_update is already easy enough to use? ;) Why was "update" chosen when you have two other forms of longer *_update() methods on sets? This is after all, a union and it's arguably more confusing not to have that in the name (especially given the "easy-to-use" other *_update() methods). > > I consider this a bug in 2.4, not a new feature, because without it, > it > > makes more work in porting applications. > > Bah.

All of the differences between set and Set were > intentional improvements (i.e. the hash algorithm's are different). I don't care about the implementation, I'm sure it's vastly superior. I'm concerned with the API. I don't agree that dropping union_update() is necessarily an improvement, but I guess I had my chance when the PEP was being debated, so I'll drop it. I do think you owe it to users to describe the differences in PLR $2.3.7 to aid people in the transition process. -Barry -------------- next part -------------- A non-text attachment was scrubbed...
