 Curious to see what the many places where !WordPress uses the ''@
 error-control operator''
 (language.operators.errorcontrol.html)
 might be hiding these days, I pasted ''Example 1 Error handling with
 set_error_handler() and trigger_error()'' of
 (function.set-error-handler.html
 into wp-config.php, pointed my browser to wp-admin/index.php here
 offline, and saw e.g.,

 It seems heavy use of the @ operator is masking at lease one or two places
 where you
 perhaps might revise the code so it wouldn't raise an error in the
 first place, and you could remove the @ operator. Or you might do
 if($x){bla();} instead of just @bla();, making the code less prone to
 mishaps.
