yeah, that's my distribution. and really, its not that hard. just make

So I created a very simple overloaded insert() method as described in
DBIx::Class::Manual::Component, in a new module called DBIx::Class::CRUD
package DBIx::Class::CRUD;
use base qw/DBIx::Class/;
sub update {
my $self = shift;
my %dirty_cols = $self->get_dirty_columns;
use Data::Dumper; # open $fh here
print $fh Dumper %dirty_cols;
return $self->next::method( @_ );
}
And in MyApp::Schema::MyClass:
__PACKAGE__->load_components(qw/PK::Auto CRUD Core/);
But %dirty_cols is empty. The DBIC::CRUD::insert method *is* being
called as a) I can dump $self to output, where there is no entry for
anything resembling get_dirty_columns, and b) entry confirmed with
$c->log->info( join "\n" => Class::C3::calculateMRO('Schema::MyClass') ):
Schema::Location, DBIx::Class::CRUD, DBIx::Class::Core, <a few more>,
DBIx::Class::PK::Auto, etc.
I'm obviously *still* doing something wrong :-(

This is a module you assisted in development? Are you suggesting I have
to write my own module to be able to use the get_dirty_columns method?

I'm quite prepared to 'dive in' if that is what is necessary. But I feel
sure it *will* be ThatHard!
