I agree Ian... good points all. ... again, I'm not arguing with anyone... just saying that an error (whatever we mean by that) should not half-way-fail.... we are only pointing out the problem... we have not idea what the solution is yet.
Intuitively everyone can see that there is a problem here... the debate cannot be answered either because of the inherent design of python (almost all of which we love). So, as they say, what is a mother to do? ... I mean, some people's kids...
I don't know how I propose to handle the problem... I think the first step is getting everyone to agree that there IS a problem... then debate how to tackle the solution proposals.
