Looks good.

This is to generalize usage of C++11 direct initialization in unordered containers.

It also avoids a number of safe iterator instantiations.

Would the following patch also make sense?

Yes, looks like a nice cleanup too.

I'll integrate it in mine and commit all the changes once tests are completed.
