Why not just return the value from the function and pass it up the
call chain? If a call fails return None. Something like this:
That's what I ended up doing but the first thing occurred to me and I
was just wondering if there's any production code that relies on the
technique.
I use the exception technique in my Python Pipelines parser. The
recursive routine has 6 raise statements. The exceptions are caught by
the program that calls the recursive routine. There would be more code
and complexity to work back up the call chain.
