Ah, I didn't understand the meaning of "discarding columns" and what it is
for. Thanks!


So, if I never want to re-select any columns, this would work?

Class->add_trigger(after_update => sub {
    my ($self, %args) = @_;
    @{$args{discard_columns}} = ();
});

If this is considered a normal idiom, I'll add it to the Wiki cookbook page.
