Re: poll: howto do informative error handling without the fatalities

I would also like to hear suggestions on how to fix this mess:

$r = funcA ( funcB ( funcC ( $p ) ) );

if funcB() / funcC() fails, how would you fudge/abort the calling
function in the chain?
One may think that funcA and funcB just check their parameters list
for being "error" arrays, but the problem i foresee is that depending
on the context of the $r= call, desired behaviour may vary at any
stage in the funcA -> funcB -> funcC chain.
