But the exception declarations ensure that you don't accidentally catch an
Exception in the wrong place, eg.
function add($amount)
{
add_money($amount) and log() or throw exception;
}
function move($amount)
{
$from->add(-$amount);
# It is *not* obvious here that this can fail and execution
# might stop here! Very dangerous!
$to->add($amount);
}
function transactions()
{
foreach ($transaction)
try { move($transaction->amount); } catch ...
}
You'd have to go function move($amount) throws SomeException, forcing
the developer to handle Exceptions at the soonest possible point...
(I'm a fan of it.)
