> 2. Matthew said that Python's engine is not robust against _unbounded_ repeated matching of an empty sub-match, and so "That's the reason for the up-front check".  I was asking for an example of _that_ behavior.  I still haven't seen one.

Perhaps Matthew did not understand you or you did not understand Matthew.
