set_error_handler and parse errors

Is it just me, or do parse errors get reported by the engine even if you use your own error handler? I've registered my own error handler with "set_error_handler()", but it doesn't get called on parse errors -- the manual seems to hint that this is the case (without actually saying it), and I searched the list archives and came across someone who hacked the PHP source to make parse errors get passed to the error handler. Anyone know for sure? Dean.
