The attached script is an attempt to get __str__ to work in rpython.
After annotation, it looks for str(someinstance), rewriting the block to call __str__.
Then the modified blocks are fed back into the annotator.
It seems to work. (And now i know a lot more about the internals of the translation process...)
I had a think about over-riding consider_op_str. It would seem natural for this code
to go there, but the annotator is not really set up to handle rewriting.
Why do i not need to manually call the flow operation on the __str__ ? (see the flow_str function)
It seems the annotator somehow must re-trigger the flowing operation when it
finds that __str__ is being called.
