Summary: evaluated code filename changed to <module> instead of ?

Initial Comment:
It seems as though the default filename for evaluated changed from "?" to 
"<module>". Was this intentional? (it's causing some test failures for me. 
The tests are correctable of course, but it doesn't seem to be an obvious 
improvement in behavior, so if it wasn't intentional, perhaps it should be 
changed back.)

1) An interpreter session is essentially a module that the user types in,
one statement at a time.

2) "?" tells me considerably less about where the error occurred than does
"<module>". "?" could mean anything.

3) Since Python 2.5 has already been released with the objected-to
behavior, I'd say it's incredibly unlikely that this change will be
reverted.

Also see

for a patch to revert to the old behavior.

Note that in the example James included, the code is /not/
in a module.

A clear improvement to me would be to say something like
<repl> or <interactive prompt> in the case James pasted and
<the name of a module> for the case of top-level code.

"<module>" is about as information-free as "?".

For me, this is indeed an obvious improvement in behaviour.
"<module>" is a much clearer indicator of where the code in
question is located; using "?" could mean that it's anywhere.
