Package:          Scripting Engine problem
Bug Type:         Feature/Change Request
Bug description:add get_error_handler and get_exception handler

Description:
------------
my co-worker had a problem with the Zend Framework Soap Server class: he
was 
using trigger_error for handling the application level errors, and the ZF
Soap 
Server class set his own error_handler, so my co-worker's error handler was

swapped out, and his E_USER_WARNING/E_USER_ERROR errors was ignored (if you
have 
an userspace error handler then every error type, which isn't observed will
be 
discarded)

I mentioned this on twitter (I wasn't really nice)
http://twitter.com/#!/Tyr43l/status/22704699030
and Matthew Weier O'Phinney responded that they had to do this, because
there 
was some quirks about the SoapServer or DomDocument class.

so if they don't set their error_handler, they can't handle the error, if
they 
do, they will overwrite any existing error_handler.

if there would be a way, to get the current(previous) error handler, then
they 
could have save the current/previous error handler (with the error type 
parameter!) and from their error handler, they could have call the applevel

error handler callback.

of course, some stackable mechanism, like the spl_autoload would be a more

better approach but that would break BC, at least I couldn't figure out a
way to 
do it without problems.

I will ask Matthew to comment on this issue (what was the exact problem
that 
forced them to set the error handler at the first place)
