Re: [Jython-dev] Edit and Continue Debugging

[Jeff A. <ja...@fa...>]

Hi Bastian:

You can modify an object from the debugger, so I guess you could replace 
a method. I think probably you don't mean that, but are referring to 
editing the source, recompiling it, and reloading it, somehow taking up 
execution at the corresponding point in the new program.

No. All the functions and methods so created would be distinct objects 
from those in your run-time context beforehand.

It would be the same in CPython. When you say: "We implemented this 
workflow prototypically in CPython." do you mean you created a modified 
CPython executable, or that it is something you find you can do with 
CPython as released?
