Please keep in mind that it is almost literally the speech that I give to my friends/colleagues when they ask me why am I so excited about Clojure. I did it many times now and I have quickly learned that saying "persistent data structures" gets misinterpreted by every single person as "something you can save to file [as XML/binary]", i.e. serialization. So the funny thing is: by changing my tune and being imprecise, I communicate the basic idea much better now :-).
I do understand and appreciate the difference (and I've watched all Rich's talks :-) but the term is so overloaded that it usually misleads "imperative" people. Only later I can introduce and use it by giving a formal definition first and letting it settle for a while. And only with people who wants to hear more and cares to learn the difference :). - Dmitry On Dec 17, 12:24 am, Laurent PETIT <laurent.pe...@gmail.com> wrote: > Thanks Richard for the good link. > > So to be even more precise, we can say that clojure's data structures are > "fully" persistent since any older version of the datastructure can still > serve as the basis to create new versions. > > 2009/12/17 Richard Newman <holyg...@gmail.com> > > > > > > I just learned (the hard way, by being humble and asking :-) ) on > > > #clojure that one does not say "immutable" collections but > > > "persistent" collections, since "persistent" conveys a lot more > > > information about what Rich has achieved than just saying "immutable". > > > Good explanation: > > >http://en.wikipedia.org/wiki/Persistent_data_structure > > > Contrast to: > > >http://en.wikipedia.org/wiki/Immutable_object > > > -- > > You received this message because you are subscribed to the Google > > Groups "Clojure" group. > > To post to this group, send email to clojure@googlegroups.com > > Note that posts from new members are moderated - please be patient with > > your first post. > > To unsubscribe from this group, send email to > > clojure+unsubscr...@googlegroups.com<clojure%2bunsubscr...@googlegroups.com > > > > > For more options, visit this group at > >http://groups.google.com/group/clojure?hl=en -- You received this message because you are subscribed to the Google Groups "Clojure" group.
