Tim, there's nothing stopping you from rethrowing errors
you don't know how to handle, eg, similar to this:
if error? set/any 'err try [print][
err: disarm err
if err/id <> 'no-arg [throw err]
]
;== none
I have *never* seen fit to rethrow errors yet, though. :)
Maybe when I start working on scheme handlers again
some day..
Regards,
Anton.
