Re: [Python-ideas] [Python-Dev] Persistent Python - a la Smalltalk
[BCC python-dev, +python-ideas] Funny you should mention this. ABC, Python's predecessor, worked like this. However, it didn't work out very well. So, I'd say you're about 30 years too late with your idea... :-( --Guido On Sat, Sep 17, 2011 at 8:05 AM, Albert Zeyer <albzey@googlemail.com> wrote:

I am not sure what he means. But if he e.g. wants to save an interactive session with the command prompt, a la Matlab, then ipython will do what he wants.
