Maybe the easiest/best way would be to have a reference to the
function itself available on the exception object?

I personally think that the easiest/best way would be for Python to use something like "<stdin-N>" as a "file" name in its repl and in exec, and use linecache to store each file. This way, the file content (and line number, etc.) could be retrieved and included in the traceback. This is often done in other REPLs (such as IPython and IDLE's pyshell).
