So, the Exception class is in the PHP5 distribution, then? Do I need to
include/require it, or is it implicit in simply running PHP5?

Next question: do I have to 'throw' an error for it to be caught? Again,
coming from perl, if I try to eval something and it fails, I don't have
to throw in error -- if one occurs, I catch it with the 'if ($@)'
construct. Is 'catch (Exception $e)' equivalent? i.e., if an error
occurs in a try block that isn't specifically thrown, will that
construct catch it?
