| Subject: | Added distinct() support for Iterator |
This is not a problem, but a first attempt at a new feature. I've included a patch with an added method distinct('methodname') to Iterator. The purpose is to return an Iterator or Array of all the items that are distinct from the original Iterator.
Example:
my $it = My::Class->search(foo => 'bar');
$it->count(); # lets say it returns 80
my $distinct_iterator = $it->distinct('myfoo');
$distinct_iterator->count(); # now returns 35
It is not very efficient as it will create the objects to run the methods, but it does get the job done.
Hope its useful.
