Is it possible to convert an object into a string that identifies the

Technically this should be possible, because things like

say everything about an object. But how can I look up the real object

I think this is the crux of my frustration. I think reload() is
unreliable and hard to validate because Python's package management is
broken. I appreciate your suggestion of alternatives and I think I
need to come to terms with the fact that reload() is just broken. That
doesn't mean it has to be that way or that Python is blameless in this
problem.

Python, where reload() is essentially the incremental build process,
and the interpreter is essentially a virtual machine, you guys are
saying that my best option is to just "reboot" the virtual machine to
