It'd be really ugly to do stuff like: $dt = $strptime->parse_datetime( $string, asa => 'My::DateTime' );
But we could do something similar with just a change in DateTime itself. We have a 'from_object' constructor -- How about adding an 'asa' method. (I call it asa because it's like isa)
$my_datetime = $strptime->parse_datetime($string)->asa('My::DateTime');
Then in DateTime.pm:
sub asa {
my ($self, $class) = @_; eval { require $class };
die($@) if $@;eval { my $newself = $class->from_object( $self ) }
die("$class is unable to accept a DateTime: $@") if $@ or not defined $newself;
return $newself; }
