We'd need to look more in detail to that question, but a quick look made me find this Java code from 2012: https://code.google.com/r/wassermanlouis-guava/source/browse/guava/src/com/google/common/collect/CompactHashMap.java?name=refs/remotes/gcode-clone/compact-maps which implements almost exactly the original idea of Raymond. (It has a twist because Java doesn't support arrays of (int, int, Object, Object), and instead encodes it as one array of long and one array of Objects. It also uses a chain of buckets instead of open addressing.) A bientôt, Armin. _______________________________________________ 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
