Well, dropping to the interactive prompt is a statement or two in Python. You could do that when something goes wrong (for example, in the inner, or outer exception handler of your application). There's also tools for Python where you can browse/modify state of a program remotely through a debugger, for example winpdb, others included in IDEs. Overall, dynamic debugging support is quite good, if you are willing to search around a bit. But probably not as good as CL or SmallTalk, if they're especially engineered for these kind of things. I don't know enough about them to comment on that.
