Hi all,

I'd like to announce a new PEP.

It is mainly codifying that Python should do what you probably already thought it did :)

Should be uncontroversial, but all comments are welcome.

Thanks for thinking about these aspects of the interpreter, and for using the PEP process to work them out before implementation. In the PEP, you mention, "some bytecodes will need to be marked as artificial, and not have a meaningful line number" (twice), but there's no example of what this means.  Can you elaborate? --Ned.
