Assuming you use Dataset#all to return the Bar instances, foos will be
eagerly loaded (that's what the tactical_eager_loading plugin does).

Both of these errors are due to the eager_each plugin. Either it should be
changed to not automatically use all for datasets without a row_proc, or
the default eager loading code should not eager load if there isn't a
row_proc. The second is a more general fix, so I'll probably do that.
