That feels kind of backwards to me ... You are wrong. The point is i am not willing to risc unstabilites with exceptions. This is a special class that heavily interacts with the executor and facilities used even after exceution hence i must be sure several intenal properties are in an exact and intact form at 100%. >> read everything just fine and you can overload you exception to print out >> better formatted output and whatever.

This has nothing to do 'violating the 10 commandments of exception'. > Couldn't you replace this with a non-final implementation that calls a > private (== final in this case) method in the default implementation ? No those are read access members to private property members. When you lok at the exception class: php -r 'reflection_class::export("exception");' then you'll encounter that you can overload __toString() and the __construct(). Or in other words you should use 'print $e' or '(string)$e' or '$e->__toString()'. -- Best regards, Marcus mailto:helly@php.net
