Hi Tom, thanks for the proposal.
As OvermindDL1 already hinted, this can lead to a slippery slope where we
need to add bang variants, question mark variants, ok/1/2/3/4 to deal with
arities and so on. I would suggest building this vocabulary as necessary in
your applications or, if you want to share it with the world, it could be a
nice library. Hint: the package ok_error seems to be available. :)
