I have a feeling this relates to the identity map solution in Rails, where all
calls are wrapped inside a DataMapper.repository(:default) { ... } block. From
DataMapper's perspective, you're inside such a block, and therefore it doesn't
check default_repository_name. Is it possible to completely override
#repository to return the one you want?
The problem, if this is the case, is that you lose the benefits of the IM, when
working with multiple repositories.
