Basically, never mix error-state and return-value. Rather use a different channel/dimension for each.
Such a separation can't be absolute though. One needs to be able to user-define routines that implement additional generic Failure related features, and in that case they WOULD be normal arguments or return values. And so the regular type system still needs to support having anything at all as an argument or return value. -- Darren Duncan
