Sorry, it seems the Google Groups web interface severely messed up the

I'd be happy with manual optimizations, i.e. some sort of explicit
marker (similar to ActiveRecord's `includes`).
So far we couldn't find any such option - among the things we tried was
"prefetching" items to take advantage of the identity map (starting in
reverse; `Lvl3Assoc.all(:Lvl2Assoc => { :Lvl1Assoc => @item }`) , but
that went nowhere...

Would this reduced test case be sufficient:

I very much appreciate your help!
