Hopefully these efforts will bring us to a solution that will do away
with the, IMO, false dichotomy between "errors" and "exceptions"
(<system_error> vs <exception>) - rather we will start thinking only
about "errors"/error objects which can be transfered in two different
ways - like a ball in a rugby game - it can be passed 'on foot' hand to
hand or it can be thrown over intermediate players to its final
destination (only with errors its in reverse - they are mostly
passed/returned or thrown 'backwards':).
IOW things like error_info will be applicable to 'the' standardized
error type(s) that functions also return, not just throw.
