6. Always log error (and backtrace) before re-raising the exception.
When you re-raise an exception, you will reset the backtrace (the track back to the line on which the error was raised) and might change the error code (if you raise a different exception to propagate the exception "upwards").
So it is extremely important to call you error logging subprogram (see previous Good to Know) before you re-raise an exception.
