I claim we need it.

But there are other reasons why you would want to see tracebacks even
if you're not actively developing.
Plenty of people distribute mostly-working code to end users and ask
them to report tracebacks. E.g. the Ultraseek product from Infoseek
(used for the python.org search) occasionally displays tracebacks.
The Zope guys also do this (they hide the traceback in an HTML comment
I believe, but it's there).
Sure, you can take a traceback without source lines and match up the
line numbers manually with your source, assuming you have the exact
version of the source -- but it's a pain.

That's no option for distributions -- the archive is the only

As I said, very inconvenient.

I didn't say I wanted *you* to code it. I just said that I want the
API. Accessing the source code is a common need in lots of places.
Adding the source to the archive is a nice solution.
Why don't you like it?
