documentation

    ProceedError is raised to indicate that a handler tried to
    proceed an exception marked as nonproceedable.

    The parameter is the exception which tried to proceed.

    NOTE: In the past ST/X didn't distinguish between proceedable
          and non-proceedable exceptions. To make transistion easier,
          this exception is a warning for now. In a future release of
          ST/X, this exception will be changed to be an error 
          (child of SignalError).
          Please fix your code.
