Hello,
What happens now borders on technologic surrealism - the CPython, after
many years of persuasion, switched its dict algorithm, rather
inefficient in terms of memory, to something else, less inefficient
(still quite inefficient, taking "no overhead" as the baseline). That
algorithm randomly had another property. Now there's a seemingly
serious talk of letting that property leak into the *language spec*,
despite the fact that there can be unlimited number of dictionary
algorithms, most of them not having that property.
