Prefetch is really smart, and in the newer versions of DBIx::Class is even capable of taking multiple relations without the risk of duplicating rows.
http://search.cpan.org/~frew/DBIx-Class-0.08205/lib/DBIx/Class/ResultSet.pm#prefetch Basically as I understood the problem, you want to fetch a row, and the "possible" relation, as a LEFT JOIN would provide. But you always want the main relation to return a value even if the join is NULL. Prefetch will do that without complicated use cases.
