+
+                It is important to remember that the standard PHP error handler is completely bypassed for the
+                error types specified by error_types unless the callback function returns FALSE.
+                error_reporting() settings will have no effect and your error handler will be called regardless -
+                however you are still able to read the current value of error_reporting and act appropriately.
+                Of particular note is that this value will be 0 if the statement that caused the error was
+                prepended by the @ error-control operator.
+
+            Smarty deliberately uses @filemtime() over file_exists() and filemtime() in some places. Reasons include
+                - @filemtime() is almost twice as fast as using an additional file_exists()
+                - between file_exists() and filemtime() a possible race condition is opened,
+                  which does not exist using the simple @filemtime() approach.
