Well, thanks for the reminder, I was *indeed* going to dump all the collections I could think of in the collections module :-) (that would have been embarassing!) Seriously, I'm curious: what needs to mature, according to you? The proposed collection is a plain MutableMapping with the single addition of transforming the key on lookup. The use cases are well-defined and well-known. If you have any concrete questions or concerns then please offer them here. > Adding yet more dictionary variants is an example of > way-too-many-ways-to-do-it. So what is your proposal for what is definitely (see examples above, and this thread's and the tracker's responses) a very common need? Keep letting people write suboptimal, incomplete, buggy versions of the same thing? Thanks Antoine. _______________________________________________ Python-Dev mailing list Python-Dev@python.org https://mail.python.org/mailman/listinfo/python-dev Unsubscribe: https://mail.python.org/mailman/options/python-dev/archive%40mail-archive.com
