Me:
That would break a lot of programs that use pickle without opening the file in binary mode.
Really? That's unfortunate.
Unfortunate, yes, and true, as far as I can see. It bit me recently -- I decided to change something to use binary pickling, and forgot to change the way I was opening the file. If you must do this, I suppose you could start issuing warnings if pickling is done without specifying a mode, and then change the default later. If there's a way of making non-binary unpickling dramatically faster, though -- even if only with cPickle -- that would be a *big* win, and shouldn't cause any compatibity problems.
