I commented on the blog post before noticing all the replies here. I'll
embellish that suggestion by suggesting that instance attributes can be as
valuable when debugging instance methods. Perhaps __trace_self__ (or
similar) could be fed from self.__dict__ if it exists?
New style formatting allows attributes and item indexes to be used:
http://docs.python.org/library/string.html#formatstrings
e.g. "{self.foo}" would render the foo attribute. So, I don't think
trace_self is strictly necessary. (If one wanted to go hogwild, one
could always just allow __trace__ to be a dictionary mapping locals
to format strings, though it loses much of the attractive simplicity
of setting a trace string.)
