I'm not quite getting it.
You *can* do joins when an explicity "join => ..." clause is passed.
What prevents Class::DBI from automatically generating this?

I.e. when you call:

my $rs = $schema->resultset('CD')->search(
   {
     'artist.name' => 'Bob Marley'
   }
);

DBIx::Class would convert the arguments, as if the user had called:

my $rs = $schema->resultset('CD')->search(
   {
     'artist.name' => 'Bob Marley'
   },
   {
      join => ['artist']
   }
);

I mean... this can be almost trivially done. Or are there some hidden
issues I'm missing?
