Raise

Feedback.Raise : exn -> 'a

Print an exception before re-raising it.

The Raise function prints out information about its argument exception before re-raising it. It uses the value of ERR_to_string to format the message, and prints the information on the outstream held in ERR_outstream.

Failure

Never fails, since it always succeeds in raising the supplied exception.
