[IPython-dev] comment on autosave

[Zoltán Vörös]

Hi Matthias,

Thanks for the comments, and I see the problems. As for overwriting the 
file, I had the impression that the problem was that some people don't 
want to bother about pressing Cntr-S. In that case, the file is 
overwritten anyway, so my suggestion was really just to make this 
mechanism automatic, without having to explicitly hit Cntr-S.

But since you have already proposed a solution in your mail on the user 
list, I wonder there would still be any point in implementing 
"write-to-disc-when-executing-cell".

Cheers,
Zoltán
