Also of interest might be the procedure ManageErrSource which makes the Err.Source property store the procedure where the error occurred.

Fine, smartypants. Powershell Try Catch Continue Terminating and Non-Terminating Errors One of the key things to know when catching errors is that only certain errors can be caught by default. If a later handler dumps the stack, you can see where the exception originally came from, rather than just the last place it was rethrown. So keepin mind that behavior might be possible.
