I don't need this case, so I can ignore it. But reliably detecting this to distinguish from other situations would be nice. > or > some_other_object.some_attribute = SomeClass() Detect that name is an attribute, handle distinctly if needed, for my purpose print 'some_other_object.some_attribute' > or > some_variable = another_variable = SomeClass() Print closest assigned variable name, i.e. 'another_variable' > or > some_variable = (SomeClass(),) There is no direct assignment.

Actually all cases that I don't need are the same case on this one - there is no direct assignment to variable. > I guess it would be better if you can describe what you really want to do. I described. Or you need use case or user story? I think I want to link object instances to variable names without to print those names (if possible) in __repr__ and debug messages to save time on troubleshooting. _______________________________________________ pypy-dev mailing list pypy-dev@python.org https://mail.python.org/mailman/listinfo/pypy-dev
