I'm not proposing any changes into the current state of thing. I'd just 
want us to be consistent with having an error status set in a case of an 
error (any error), so that the system we have in place (%exception in 
cpl_exceptions.i) can catch error situations. I don't know Python's 
system enough to know what you are talking about, sorry :)
