Just a quick update.I've been analysing and profile the behaviour of my new dict and messing about with various implementation options.I've settled on a new implementation.Its the same basic idea, but with better locality of reference for unshared keys.Guido asked: > Another question: a common pattern is to use (immutable) class > variables as default values for instance variables, and only set the > instance variables once they need to be different. Does such a class > benefit from your improvement?For those instances which keep the default, yes.Otherwise the answer is, as Martin pointed out,it could yes provided that adding a new key does not force a resize.Although it is a bit arbitrary when a resize occurs.The new version will incorporate this behaviour.Expect version 2 soon.Cheers,Mark.
