Well, I'd be interesting how it goes, since if Jython users find this acceptable then maybe we shouldn't be quite so concerned about it for CPython... On the third hand we don't have working code for this approach in CPython, while we do have working code for the PEP 393 solution...

I, for one, am very interested. It sounds like the 'unicode' datatype in Jython does not in fact have O(1) indexing characteristics if the string contains any characters in the astral plane. Interesting. I wonder if you have heard from anyone about this affecting their app's performance? So far we haven't had any complaints - I'm not really sure how often Jython gets used with astral plane characters at this point, but I expect it will happen more in the future, especially once we put together a Jython 3 and Unicode support becomes a stronger expectation. Personally I'm hoping that in that time frame Java will come under pressure to provide a better answer (or we may need to think in the same direction as Dino was thinking in an earlier part of this thread and make a more Python specific String type for Jython....) -Frank
