Thank you for explaining. I'm glad I wasn't the only one confused by the original post :) I think this is a nice-to-have, rather than being a serious bug to be fixed. When you get an error about a function call, it's entirely possible that the target function is the problem, or that the wrong function is being referenced; but you can get similar problems with all kinds of mismatches (like "a, b, c = thing" and getting a ValueError - maybe you'd need to check the line where 'thing' originated). If this can be done easily, great, but otherwise it might be the domain of traceback enhancement tools rather than the core language. Does execution ever (in the normal case) actually hit the 'def' line? If so, I wouldn't be averse to having a traceback line mentioning it. But if (as I suspect) tracing successful execution wouldn't hit that line, then it doesn't seem right to feign execution of it. My understanding of the def statement is that it runs ONLY when the function is defined; when the function's called, you go straight into the body.
