Not knowing the internal of tkinter, this seems somewhat confusing.
Is that an "anonymous name/id"?

> <tkinter.Button object .panel.b1>

This already looks more useful.  How is that determined?  Why the "first" object is missing (i.e. .panel seems to be an attribute of a missing object)?


Regarding the patch, are you sure that .__class__.__module__ is always available?  I seem to remember that it might be missing in some cases, e.g. modules written in C (but I might be confusing it with something else like __file__).
