Rubbish, whatever gave you that idea?
Docs say:
|prefetch| can be used with the following relationship types: |belongs_to|,
|has_one| (or if you're using |add_relationship|, any relationship declared
with an accessor type of 'single' or 'filter').
Then docs are bork, which doc is that?
You can now fetch a has_many quite happily, the only thing that doesnt
work, iirc, is fetching 2 has_manys at the same level.
You can indeed prefetch a has_many rel.
Excellent. How does that work? Do you get one instance of each object with a
prepopulated resultset?
Err, it works just like you called the rel, so if you fetched author and
prefetched books, then $author->books in scalar context is a resultset
with no extra query, and in list context its a list with no extra query.
