What do people think parsers should return if they can't parse? And what if they do parse, but DateTime doesn't want to create an object of the appropriate specification?
DateTime::Undef :)
If all modules return DateTime::Undef and all modules handle it when passed it, then everything flows.
If we return undef, then we need to make sure all methods can handle undef parameters cleanly. Of course, we really can't do this because:
undef->set( day=>$day )
is an error .. no matter what!
However:
$undef = new DateTime::Undef;
$undef->set( day=>$day );
just returns DateTime::Undef;Cheers! Rick
